Yoga Sutra 4.29 the samadhi called Raincloud of Dharma

Sūtra IV.29

For one who is through and through a man of discriminative knowledge, but is not grasping over his meditation practice, there comes about the samādhi called Raincloud of Dharma

When a Brahmin has a mind moving towards Knowledge-of-the-difference, For one, who is through and through a man of discriminative knowledge but is not grasping over his meditation practice (prasaṅkhyāna), there comes about the samādhi called Raincloud of Dharma. This Brahmin is not grasping over, not seeking profit from his meditation, which is practice of discriminative vision, and does not seek for anything even from that, other than the special serenity of meditation practice. The word ‘even’ means that even in his meditation he has no desire for anything; he is detached even from that meditation, through and through, in everything, he has Knowledge-of-the-difference, he is a man of discriminative Knowledge alone.

Because the saṃskāra-seed of taint is destroyed, his body is as it were an empty house (Gītā V.13 and Śaṅkara Bh.), and for him who has his home in the serenity of Knowledge alone, no other ideas are created. Then, for that one, for that Brahmin who is through and through a man of discriminative Knowledge, there comes about the samādhi called: Raincloud of Dharma. It rains the supreme dharma called Transcendental Aloneness – hence this technical name.
