In which one knows that infinite bliss which is apprehended by the intellect and is beyond the senses — where, established, one does not deviate from the truth.

The ānanda (bliss) of samādhi: ātyantika (supreme, final), buddhi-grāhya (accessible to buddhi, not to inferior senses), atīndriya (transcending senses).

Once established (sthita), the yogi “does not move” (na calati) from the tattva (truth/reality). It is a stable state, not a passing experience.
