Śivasaṃhitā 5.78

Mṛtyum bhakṣayati—“devours death”—is the svādhiṣṭhāna’s most potent promise: the practitioner not only overcomes death (mṛtyunjaya) but consumes it, inverting the ordinary relationship where death consumes the living being. This radical inversion reflects the yogic understanding that fear of death (mṛtyubhaya) is the root of all other fears, and that the sacral chakra—where reproductive and survival energies are managed—is precisely the point where this fear anchors itself in the body.

Aṇimā and laghimā—the first two of the eight great siddhi (aṣṭamahāsiddhi)—are the capacity to become extremely small and the capacity to become extremely light, respectively. Their appearance as a result of svādhiṣṭhāna meditation is not description of literal magical powers but of transformations in the practitioner’s relationship with his own body: the experience of being able to contract to the smallest point of consciousness and expand to the lightness of space are verifiable meditative states.

Amṛta—“the nectar of immortality”—increasing in the practitioner connects to the doctrine of candra bindu (lunar point) in ājñācakra: the soma or pituitary gland that distills the nectar of immortality during deep prāṇāyāma. This nectar (sudhā) is described as the reverse of the ordinary aging process: instead of digestive fire consuming vitality, amṛta regenerates it. Meditation on svādhiṣṭhāna accelerates this regeneration process.
