The first six verses reveal the mantra of Amṛteśvara Bhairava.
The seventh verse describes the śakti of Lord Bhairava. Arising from the navel of Amṛteśvara Bhairava is the śakti triśūla (trident) on the left prong of which is stationed Aparā Devī. Parāparā is stationed on the right prong and Parā on the central prong. Above the central prong, Mahākālasaṅkarṣiṇī Kālī is present who is known as Parātītā Bhaṭṭārikā. The seventh verse above describes mukhya śakti of the three [Parā] also known as Amṛteśvarī.
While the mantras of Amṛteśvara Bhairava, Parāparā, Aparā and Parātītā Bhaṭṭārikā are to be received from Sadguru through the process of initiation or Dīkṣā, the votaries of Kashmir Shaivism hold that the mantra of Parā, also known as Devī Hṛdaya Bīja is the only mantra which can be recited without initiation from the Guru. Of course, this is not accepted in śrīvidyā where Parā Bīja requires specific initiation (as detailed in Parā Tantra, Paraśurāma Kalpasūtra etc.) from the Guru and one receives this mantra only after completing puraścaraṇa of several other mantras including Pañcadaśī and Laghu-ṣoḍaśī.
