Kaivalya Pada

Only the minds born of meditation are free from karmic impressions.
—Kaivalya Pada: Sutra 7.

Since the desire to live is eternal, impressions are also beginningless.
The impressions being held together by cause, effect, basis and support, they disappear with the disappearance of these four.
—Kaivalya Pada: Sutra 11-12.

Kaivalya, which is the ultimate goal of yoga, means solitariness or detachment. The 34 sutras of the fourth chapter deals with impressions left by our endless cycles of birth and the rationale behind the necessity of erasing such impressions.

It portrays the yogi, who has attained kaivalya, as an entity who has gained independence from all bondages and achieved the absolute true consciousness or ritambhara prajna described in the Samadhi Pada.

…Or, to look from another angle, the power of pure consciousness settles in its own pure nature.
—Kaivalya Pada: Sutra 35.
