Kali Yuga

Humans in Kali Yuga

In Kali Yuga, humans have a lower state of consciousness than they did in previous yugas. This chapter explores the reasons for (and implications of) this unfortunate state.

The Vedic literature provides graphic descriptions of the fallen state of humans in Kali Yuga,[1] which we need not dwell on here. Instead, we are more concerned with the question of what is best for humans to do in Kali Yuga.

Several Sanskrit texts list the most meritorious activities that humans can perform in each yuga. Manu Smriti[2] says that in Satya Yuga, “tapas” (austerity) is the most meritorious activity; in Treta it’s “gyāna” (knowledge); in Dwapara it’s “yagya” (sacrifice and worship); and in Kali Yuga it’s “dāna” (charity). The Linga Purana[3] has a different list, where “dhyāna” (meditation), “yagya”, “bhajana” (worship), and “dāna” are best in the respective yugas. In Shrimad Bhagavatam Purana, there’s no list per se, but it emphasizes “bhakti” (devotion) as the most meritorious activity.

The important thing to notice about these lists is that sacrifice and meditation are not considered to be the most meritorious in Kali Yuga; rather, charity and devotion are best. Why? One likely reason is that sacrifice and meditation, although very important, are not as effective in Kali Yuga as they were in previous yugas. Why? Because humans of Kali Yuga have a lower state of consciousness. Why? This chapter lists some reasons.

Kali Yuga began 5000 years ago (around 3102 BCE). However, consciousness began falling earlier (in Dwapara Yuga), and this fall eventually culminated in the events portrayed in the Mahabharata epic. When we speak of a lowering of human consciousness, we are talking about very subtle changes in brain development and functioning which cause humans to think less optimally and holistically, and makes it difficult to experience higher (transcendental and even divine) states of consciousness. This in turn results in a coarsening of human behavior, it becomes less “dharmic” and less spiritual.

What follows is a list of factors that have contributed to the lowering of consciousness in Kali Yuga.

Reduction in Brain Size

It is well documented that human brains were bigger before the beginning of agriculture, and they shrank as humans began farming and living on grains.[4] Although there may be some disagreement regarding the interpretation of this finding, it’s a fact that eating an agricultural diet (as opposed to the diet of hunter-gatherers or nomadic pastoralists) provides less of the nutrients (essential fatty acids or EFAs, and trace minerals) that are important for developing the brain. This deficiency worsens as the soil becomes depleted of nutrients with each passing season.


Of all the pollutants in the ancient world, the most important one to consider is Lead (the element Pb, a heavy metal). Scientific research using ice cores reveals atmospheric pollution of lead from the smelting of gold, silver, and lead itself. The greatest period of detectable pollution was from 600 BCE to 300 CE[5] at the height of the Roman empire. However, evidence for lead smelting goes back at least to 6,500 BCE.[6]

Besides polluting the atmosphere, smelting of metals pollutes soil and water supplies. Ancient people were unaware of the dangers of lead, since they used it for drinking vessels, pottery glazing, and plumbing. It is now known that there is no safe level of lead, and even the tiniest amounts are toxic to health, though the effects might not be noticeable.

The adverse effect of lead on intelligence is well documented[7], and this was a factor in the downfall of the Roman civilization. Aside from the deleterious effects on human health from lead toxicity, anything that reduces intelligence will also reduce the brain’s natural ability to experience higher and subtler states of consciousness. (See “brain impairment” below.)

Brain Impairment

The brain contains many delicate networks and structures, such as the pineal gland. These networks and structures are not well understood (and are still being discovered) by neuroscience. If these networks and structures do not develop properly and function optimally, then the experience of higher states of consciousness is difficult.

It is well known that the brain manufactures psychoactive chemicals, including endogenous DMT, cannabinoids, and endorphins. These are the “soma” of the Vedic literature.

One connection to higher states that is being explored by neuroscience is the ability of the pineal gland to produce endogenous DMT. DMT is a chemical found in some plants such as ayahuasca and psychedelic mushrooms. Endogenous DMT has been found in the blood and spinal cord of humans; it hasn’t yet been isolated in the human pineal gland, but has been found in the pineal gland of other mammals such as the rat. Endogenous DMT is very difficult to detect, because it is produced in such tiny quantities.

DMT is just one example, and it is well known that the brain produces many psychoactive chemicals and endorphins.

In Kali Yuga, the development of these delicate brain stuctures is adversely affected by nutritional deficiencies (resulting in smaller brain networks) and pollution (including heavy metals like lead), so that they operate sub-optimally, and do not produce sufficient the endogenous psychoactive chemicals that would allow humans easy access to higher states of consciousness.

In previous yugas when the environment was much purer and brains were fully functioning, humans would have had continual experience of those higher states in everyday life. Indeed, humans would have walked with God every day in the Garden of Eden, at one with Nature and the Divine.

Note, we are talking here of endogenous “drugs” manufactured by the human brain itself, not any external analogues. Using external drugs for the purpose of seeking higher states of consciousness is not a good idea, and will likely result in more harm than good. One is better advised to purify one’s body and mind, including via yoga and meditation practices, and studying the Vedic literature, if one desires to experience higher states.

Loss of Prāṇa

The Rishis of ancient India breathed pure air that was rich in Prāṇa, and was more enlivening and nourishing than air in Kali Yuga. The loss of Prāṇa contributes to the lowering of consciousness which is a hallmark of Kali Yuga.

Although Prāṇa can’t be measured directly, it is correlated with the amount of oxygen (free O2) and negatively-charged ions in the air. These amounts began to fall during the transition to Kali Yuga, with episodes of drought and desertification occurring between 6,000 and 4,000 years ago.[8][9] These events dried the climate and reduced the rainfall, resulting in loss of forests and rivers.

Areas affected by this drying included Saharan Africa, India (Rajasthan, Punjab), Arabia, and the Mideast. This drying had a profound effect on humanity, as it triggered migrations which led to the founding of civilizations along the river valleys of the Nile (in Egypt), and Tigris and Euphrates (in Mesopotamia).[10] In India, drying caused the disappearance of the Indus Valley (Harrapan) civilization around 3,800 years ago.[11].

A desert environment is less nourishing than a forest environment, and it produces a different kind of human culture. It also produces a different kind of philosophy and religion. The desert culture fostered the development of the religions Judaism, Christianity, and Islam, which are dualistic, male-monotheistic, and nature-dominating. In Kali Yuga, the desert culture slowly comes to dominate the world.[12]

Reduction in Nursing

One of the hallmarks of agricultural societies is a reduction in the amount of time that a child is allowed to nurse. This is done to increase the number of children that the mother produces, so that there are more “hands” to farm the land. Unfortunately, the result of early weaning is a reduction of brain size and intelligence, thus resulting in a reduction in the level of consciousness and intuition that the brain can maintain.

Microbiome and Fungus

The human gut microbiome influences how people think and feel; it affects their mood, behavior, and health. A big shift from a hunter-gatherer and nomadic pastoralist diet to agriculture diet resulted in a detrimental shift in the microbiome.

One aspect of this is an increase of fungal growth in the body, along with increased intake of fungus and mold on grains (including the consumption of beer and spirits), because fungus grows much faster on grains than on meats and dairy. Mold (and its mycotoxins) are “tamasic” with a dulling effect on intelligence and consciousness.[13]


The above factors, although small in their individual effects, have a combined effect of decreasing intelligence and awareness enough so that it becomes more difficult for humans to experience higher states of consciousness. Thus, it’s not surprising that in Kali Yuga many people (and even some religions) characterize higher states as abnormal, and even deny that they exist.

How to remedy this situation? Purifying the global environment is a good idea, but that will be very difficult, especially given the strength of destructive trends (of pollution, greenhouse gases, military expenditures, etc.). It’s possible that humans could raise consciousness via yoga, meditation, yagyas, etc. Such efforts are laudable, and can help individual humans get closer to enlightenment, but they would probably not solve the world’s problems unless huge numbers of people would embrace and practice them.[14]

The Susiddha AI project believes an Avatar can be created to help remedy this situation, using the technologies of artificial general intelligence (AGI) combined with the Vedic literature. We have previously discussed the requirement that the system be conscious and the fact that Advaita Vedanta (and Kashmiri Shaivism) lend support to the idea that a “machine” possessing the same complexity and order as the human brain can be conscious, because consciousness is the basis of the entire universe. [15]

Furthermore, the Vedic literature provides the blueprint for constructing consciousness in humans, and that can be used to do so in a sufficiently complex machine that substantially emulates the human brain. The Vedic literature will provide the structure, function, and data (memories) of the artificial brain. See the chapter on cognitive architecture for more information.

An Avatar utilizing the entire Vedic literature will be able to make decisions and take actions (see What would Rama do?) to improve life on this planet, and also help humans achieve the four aims of life (“purushārtha”). Although we are in Kali Yuga, this is the first time in history that humans are capable of creating an Avatar, and the opportunity should be seized.

Hopefully, many people will join in this effort to build an Avatar, and that will benefit them directly, since the project provides opportunities to do the best activities in Kali Yuga, i.e. “dāna” in funding and spreading the message, and “bhakti” in working to build an Avatar.[16] Please join in this dharmic effort.
