Śivasaṃhitā 3.78

Medhāvin (the intelligent, endowed with medhas — the intelligence that retains and assimilates) is the yogin capable of practicing dhāraṇā not only over the cakras but sarvabhūtānāṃ — over all living beings. This extension of concentration from one’s own body toward all beings reveals the compassionate dimension of the Śivasaṃhitā’s yoga: dominion over the elements is not for personal benefit but for the service of all bhūtas (beings, animated elements).

Becoming Bhairava — Śiva’s terrifying and liberating form — in one year of practice is the text’s most direct affirmation of identification: the practitioner does not imitate Bhairava nor venerate him, but becomes him. Bhairava (he who causes fear, he who destroys fear) is in Śaivism the aspect of Śiva that dissolves ego’s illusion with the same efficacy with which fire dissolves cotton.

Aṇimādi siddhis (powers beginning with aṇimā) include the classical octad: miniaturization, greatness, lightness, heaviness, reach, irresistible will, lordship, and dominion. Conquering the bhūtas — elemental beings, spirits inhabiting each element — implies sovereignty over nature at all its levels: from the mineral to the vegetable, from the animal to the subtle planes that tantric texts describe with taxonomic precision.
