Śivasaṃhitā 3.53

Two qualities defining the advanced yogin by their absences: arogitva (absence of disease, intrinsic health) and adīnatva (absence of despondency, absence of meanness or depression). Dīna in Sanskrit designates both material poverty and the mental state of one who feels small, insignificant, crushed by circumstances. The truth-perceiving yogin knows neither form of this state.

Tattvadarśin (one who sees the tattvas, who perceives the essential truth of things) reappears as designation of the yogin who has reached a genuine threshold of realization. In Sāṃkhya-Tantra cosmology, the tattvas are the twenty-five — or thirty-six, in the Śaiva version — constituent principles of reality. Seeing the tattvas is seeing the actual structure of experience, without ego’s distortion.

Three gharis of retention (approximately one and a half hours) is a technically extraordinary goal. One ghari equals approximately twenty-four minutes in the classical Indian time system. The text establishes this capacity as the threshold for access to siddhis: not as a promise of extraordinary capabilities but as a physiological indicator that the practitioner’s nervous system has been fundamentally reconfigured by practice.
