⁷⁵ Suṣumṇā, located in the brahmarandhra, on the road to final liberation (muktimārga), is invisible (avyakta) and associated with Viṣṇu (33). The three main nāḍīs are Iḍā, Piṅgalā and Suṣumṇā; Suṣumṇā is foremost among them (34). Iḍā runs on the left side, Piṅgalā on the right side, and Suṣumṇā in the middle; all three are pathways of vāyu (35). Iḍā has the lustre of a conch and the moon, Piṅgalā is white and red (36). Iḍā is a seat of the moon, Piṅgalā of the sun, Suṣumṇā of the wind (marut); Iḍā is a seat of rajas, Piṅgalā of tamas, Suṣumṇā of sattva; Iḍā is associated with the day (37). Iḍā has the nature of vāyu, Piṅgalā that of fire, while Suṣumṇā, lying on the pathway to the brahmadvāra (= brahmarandhra), has the nature of both (38).
