The 12th chapter is a sadhana (Բ or “perfect realization�) of ղḍāk (vajraḍākasyaԲ). More precisely, it is a manual of meditation to visualize a mandala (ṇḍ) consisting of the supreme deity named ղḍāk and his retainer deities.
According to the Vivṛti, [regarding the Բ of ղḍāk], the deity ղḍāk is dark-blue, is greatly terrifying, is adorned with a wreath of skulls (첹), has four arms, has four faces with three eyes on each, is shining, is dancing on the sun disk on a human corpse, and holds a skull bowl (첹), a skull staff (ṭvṅg), a bow (dhanus) and an arrow (ṇa) with his four hands.

Accordingly, the vajracakra refers to one of the four divisions of the Ჹ-ṭa (‘innate layer�), situated within the padma (lotus) in the middle of the Herukaṇḍ. The 36 pairs of Ḍākinīs and Vīras [viz., ղḍāk] each have one face and four arms; they hold a skull bowl, a skull staff, a small drum and a knife; they are dark-bluish-black in color.

The Upahṛdaya-mantra consists of seven letters. [...] The purity of these seven deities [viz., ղḍāk] is the Seven Limbs of Enlightenment (ǻⲹṅg).

Tibetan Buddhism includes schools such as Nyingma, Kadampa, Kagyu and Gelug. Their primary canon of literature is divided in two broad categories: The Kangyur, which consists of Buddha’s words, and the Tengyur, which includes commentaries from various sources. Esotericism and tantra techniques (Բ) are collected indepently.
