Yogi is freed from the grip of nature.

Verse 4.30

ततः क्लेशकर्मनिवृत्तिः ॥३०॥

tataḥ kleśa-karma-nivṛttiḥ ||30||

From that comes cessation of pains and works.

From this rain-cloud of virtue, afflictions cease of their own accord and in their place, divine actions with no reactions flow forth like a river from the yogi. This is freedom.

Avidya, the mother of afflictions, is eradicated, root and branch, along with residual subliminal impressions. The sadhaka will not now deviate from the path of divinity nor perform an act that binds, hinders or preconditions

his consciousness. He is free from the bondage of karma. In the Bhagavad Gita (vi.5), Lord Krishna says that each individual has to cultivate himself to become enlightened, and to learn not to degrade himself, for the Self alone is the friend of the individual self, and the Self alone is the enemy of the egotistical self.

As the light of a lamp fades as the oil runs out, so the lamp of the mind is extinguished as its fuel, the actions producing joys and sorrows, is exhausted.

As nirmana citta is extinguished of its own accord, its root motivation is burnt out leaving no opportunity for the production of effects. The cycle of cause and effect is at an end, and the yogi is freed from the grip of nature.

Even in this liberated state, he will not forego his practices. He will continue to maintain them as a divine command, so that the freedom earned may not be lost by neglect''.
