Power of environment is the great check to control even Karma itself.

Verse 4.8

ततस्तणिऩाकानगुिानाभ ु एवाणबव्यणिवा ् सनानाभ

य ॥ ८ ् ॥

tatastadvipakanugunanam evabhivyaktirvasananam

From these threefold works are manifested in each state only those desires (which are) fitting to that state alone. (The others are held in abeyance for the time being.)

Suppose I have made the three kinds of Karma, good, bad,

and mixed; and suppose I die and become a god in heaven; the desires in a god body are not the same as the desires in a human body. The god body neither eats nor drinks; what

becomes of my past unworked Karmas, which produce as

their effect the desire to eat and drink? Where would these Karmas go when I became a god? 

The answer is that desires can only manifest themselves in proper environments. Only those desires will come out for which the environment is fitted; the rest will remain stored up. 

In this life we have many

godly desires, many human desires, many animal desires. If I take a god body, only the god desires will come up, because for them the environments are suitable. And if I take an animal body, only the animal desires will come up, and the god desires will wait. What does that show? That by means of environment we can check these desires. Only that Karma which is suited to and fitted for the environments will come

out. 

These proves that the power of environment is the great

check to control even Karma itself.
