Śivasaṃhitā 5.155

This verse introduces the citrā nāḍī, the innermost and most luminous channel within the suṣumṇā, linking its activation directly to the fullness of samādhi. The progression is significant: the practitioner moves from the gross body inward through successive layers of subtlety—suṣumṇā, vajriṇī, citrā—until consciousness dissolves into the divine ground. Firmness (sthairya) is the fruit of this complete absorption.

The word citrā (brilliant, wondrous) describes a channel of pure luminosity, often equated with the brahmanāḍī in texts like the Ṣaṭcakranirūpaṇa. Kula, in the Kaula tantric tradition, refers to the totality of Śakti’s manifestation—the entire web of energy that constitutes reality. Absorption in Kula is therefore not withdrawal from the world but recognition of its innermost nature as divine energy.

The address mama vallabhe (oh my beloved) places this teaching within the Śiva-Pārvatī saṃvāda genre, a dialogic form pervasive in tantric scripture. Far from being decorative, this framing encodes a pedagogical principle: the deepest teachings are transmitted in intimacy and trust. The Śivasaṃhitā consistently employs this device to signal that what follows is esoteric knowledge, reserved for the qualified and devoted practitioner.
