Execution of Śakticālana: repeated contractions of the perineum while retaining the breath and visualizing energy ascending.

“Causer of the rising of kuṇḍalinī” is the specific function. While other practices prepare, this one directly awakens the dormant energy.

Repetition (muhur muhuḥ) is key. The awakening does not occur all at once; it requires sustained stimulation until the energy “leaps” and begins to ascend on its own.
