Śivasaṃhitā 5.193

The culminating moment of kuṇḍalinī yoga is described in terms of stillness, not explosion: the śakti called kula «enters laya», dissolves. The serpent’s fire does not blaze—it extinguishes itself in the sahasrāra’s ocean of consciousness. This laya is the consummation of all practice: the energy that ascended from the mūlādhāra finally merges with its source.

Atra = here (in the sahasrāra), kuṇḍalinī-śakti the coiled śakti, laya dissolution/absorption, yāti goes/enters, kula-abhidhā called kula (one of kuṇḍalinī’s names in the kula-mārga tradition). The homa (ritual fire, hom = offering to fire) of one hundred thousand repetitions is the external parallel of the internal fire.

The homa practice in this context belongs to the puraścaraṇa (ritual preparation) stage that precedes full reception of the mantra’s power. The tantric tradition requires that before the mantra «lives» fully in the practitioner, a determined cycle of recitations, oblations and purificatory rituals must be completed. This formal rigor contrasts with the apparent simplicity of kuṇḍalinī’s dissolution.
