Śivasaṃhitā 3.10

With adhunā («now»), the text pivots to a new section, marking the rhetorical transition characteristic of Sanskrit treatises. The word kṣipram («quickly», «without delay») is striking: it suggests that the path about to be revealed is not one of prolonged austerity but of direct efficacy — a recurring promise in Haṭha Yoga literature, aimed at practitioners seeking a reliable and expedient route.

Siddhi in yogasya siddhaye carries multiple resonances: «success», «perfection», and «supernatural power». The polysemy is deliberate. Success in yoga is not merely technical but ontological, a transformation of being. The verb kathayiṣyāmi («I will tell», «I will narrate») situates the text within the oral guru-disciple transmission tradition, even as it appears in written form — the teacher speaks; the text is his preserved voice.

This type of introductory verse (upakrama) serves a precise rhetorical function in śāstric literature: it captures attention, promises concrete results, and legitimises what follows. The guarantee that yogins «never fail» operates as a seal of authority, inviting the practitioner-reader to trust the method about to be expounded, a trust that the subsequent sections on āsana and prāṇāyāma will be expected to justify.
