In Vedic literature and theory they say we are in the Kaliyuga which is described as one of degeneracy, immorality, decay and increasing chaos.
Take for example the following:
Śrīmad Bhāgavatam 12.2.1
tataś cānu-dinaḿ dharmaḥ
satyaḿ śaucaḿ kṣamā dayā
kālena balinā rājan
nańkṣyaty āyur balaḿ smṛtiḥ
Śukadeva Gosvāmī said: Then, O King, religion, truthfulness, cleanliness, tolerance, mercy, duration of life, physical strength and memory will all diminish day by day because of the powerful influence of the age of Kali.
One need not point out this is NOT a Buddhist text. However, that need not negate the value of such predictions. You don't have to be a Buddhist yogi to develop foreknowledge and wisdom. In the Buddhist model such individuals may perhaps not achieve liberation from samsara, but they still can possess a divine eye.
In Buddhism of course one also finds the Buddha by his own admission describing the eventual decay of his dharma in the world. There has been endless discussion over the centuries when precisely this degenerate age will begin. Nevertheless it is certain that degeneration was foretold.
As I read more of traditional Indian (not necessarily "Hindu" because such a concept only began in the 19th century) ideas on the kaliyuga I find myself thinking how it describes our present day. The quote above accurately describes what is happening to our world. The idea of kaliyuga actually helps in explaining a lot of things in the world and in human history. However, unfortunately it also leads me to wonder what can be done.
In such times the Bodhisattva presumably finds their calling and duty to lead from the front, but then looking at it realistically rather than idealistically there is only so much one can do given the circumstances.
I often see quick rejection of such an idea as the common view now amongst many Buddhists I dialogue with is that that Buddhadharma is spreading across the planet, science is purportedly fixing so many of our problems, some historians insist the standard of living is going up and "democracy" allows for much more freedoms and liberties than in past ages. However, such assertions are debatable when you take a good realistic look at the world. I would argue things are getting worse and worse both on religious and social levels.
I mean look at the life expectancy assumption. We think we live longer than before but that's misleading. The life expectancy from birth fails to take into account all humans. The statistic should be recalculated as life expectancy from conception and then factor in abortion numbers. If you factor in the probability of an individual being aborted within the first eight to nine months of their existence from conception, the average human life expectancy I imagine would decrease dramatically. In our present day where abortion is common and even enforced by law in some countries, the people of old probably statistically lived longer on average.
Incidentally, this is where religious teachings would increase life expectancy. Reduce abortions and average human life expectancy from conception would increase.
However, by present day definition you're only a human individual from birth.
This all has great implications on how one might plan life and make decisions. Whether you agree or not, there is plenty of good evidence to support the claim that we're in the kali yuga and all the signs of it are present and increasing.
