Description of the Svādhiṣṭhāna cakra: the second lotus, situated at the root of the liṅga, is the great light kept secret in all the Tantras.

The Svādhiṣṭhāna is situated «at the root of the liṅga», a location that reveals its nature as center of creative and generative force. Calling it «the great light secret in all Tantras» elevates this cakra description to the level of a central mystery: not merely a step on the scale, but a secret the Tantras have kept with special care.

Sva means «own» or «one’s own», adhiṣṭhāna «abode» or «seat» (adhi = above, sthāna = place), making Svādhiṣṭhāna literally «the abode of the self». Saroja is the lotus (sa = with, roja = red color), liṅga-mūla the base of the liṅga. Parama-prakāśa is the supreme light, the primordial radiance.

The Svādhiṣṭhāna’s location varies between texts: the Śiva-saṃhitā situates it «at the root of the liṅga», while the Haṭhayogapradīpikā describes it in the sacral region. This difference reflects subtle body mapping traditions emphasizing distinct aspects: the former underscores the energetic-sexual dimension, the latter the anatomical one. Both perspectives point to the same center of creative energy.
