Śivasaṃhitā 5.58

The double serpentine image of Kuṇḍalinī in this verse illuminates her nature from two angles: as sleeping serpent (suptā nāgopamā) it evokes latent potential, power resting in itself without manifesting; as serpent living between the joints (sandhisandhau) it evokes energy that filters through the junctions between vertebral bodies, animating the spine from base to skull. The serpent is not an arbitrary image: it captures the sinuous, undulating, and potentially awakeable nature of this energy.

Svayambhūlinga—the self-born liṅga, spontaneously self-generating energy—in the Śaiva tradition is Śiva’s manifestation in mūlādhāra as pure creative potentiality. Kuṇḍalinī as goddess of speech (vākdevatā) connects to the doctrine of vāk (speech/the Word) in Kashmir Śaivism: the energy ascending through the chakras is the same that articulates language, from the most subtle level (parāvāk) to the most manifest (vaikharī).

Kuṇḍalinī’s own luminosity (svayaprabhā) is a central feature: she does not reflect light from an external source but is herself a source of light. In tantric iconography, Kuṇḍalinī often appears as golden or reddish light at the base of the spine. This self-luminosity identifies her with cit—pure consciousness that is its own source of illumination—and anticipates the nature of the liberated state where the yogin also becomes a source of self-generated light.
