Yugadharma & Entropy

These are found in Parasara Smriti (100 A. D.)

The first Yuga was Kritayuga, where austerity was most important. People were truthful & curses would take effect immediately. Wealthy would themselves approach the needy & help. Righteousness was complete.

The second, Tretayuga held knowledge paramount. People would avoid sin & curses would take effect within 10 days. Wealthy would invite needy & help them. Righteousness was only three quarters.

The third, Dwaparayuga, Vedic rituals would predominate. Sinners would be cast off & curses would take a month to be effective. Poor would be helped only if they begged for it. Righteousness was only half.

The fourth, Kaliyuga had only a quarter of righteousness & giving charity was
most important. Sinners were considered depraved & curses would take a year. People were helped only if they rendered service first. Righteousness was only a quarter.

It can be observed that so-called human qualities gradually lessened in the four yugas, tending towards chaos.

Entropy is defined in thermodynamics as the degree of molecular disorder or state of randomness of a system, leading to chaos. The arrow of Entropy & the arrow of time always point in the same direction.

So the Hindu system of cosmology may be looked upon as an Entropy applied to human behaviour. But the difference is, while the arrows of time & Entropy point in the same direction, making it a linear function, Hindu cosmology is essentially cyclic in nature, bringing back the sublime heights of Kritayuga after the deplorable depths of Kaliyuga.
