FAQs
It teaches that when an action is aligned with Śiva’s intent (Śambhu-kṛta), the primary means is disciplined mantra-japa, and the final accomplishment comes by Śiva’s grace—Pati completing what the limited self cannot.
Koṭi-japa is typically undertaken before or alongside Saguna worship—such as Linga-pūjā—where repetition of Śiva’s name/mantra invokes Śiva’s presence and makes the devotee fit to receive His anugraha (grace) that fulfills the intended purpose.
A vow of mantra-japa (often the Pañcākṣarī “Om Namaḥ Śivāya”) for one koṭi repetitions, ideally supported by purity disciplines and focused meditation on Śiva as the compassionate Lord who completes the sādhaka’s work.
