Triśakuni (त्रिशकुनि) is the name of a sacred site (pīṭha) presided over by Vāyuvegā, according to the vārāhyabhyudaya-maṇḍala. Vāyuvegā is a deity situated in one of the six petals of the northern lotus, of which the presiding deity is kuleśvarī (presiding lady) named Locanā. The central deity of the vārāhyabhyudaya-maṇḍala is the twelve-armed Vajravarāhī.

Triśakuni is one of the twenty-four pīṭhas, or ‘sacred-site’ (six lotuses each having six petals), each corresponding with a part of the human body. Triśakuni is to be contemplated as situated in the navel. Besides being associated with a bodily spot, each pīṭha represents an actual place of ancient India frequented particularly by advanced tantric practitioners

Vākcakra is one of three Cakras within the Tricakra system which embodies twenty-four sacred spots or districts (viz., Triśakuni) resided over by twenty-four ‘sacred girls’ (ḍākinīs) whose husbands abide in one’s body in the form of twenty-four ingredients (dhātu) of one’s body.

Triśakuni has the presiding Ḍākinī named Vāyuvegā whose husband, or hero (vīra) is named Mahāvīra. The associated internal location are the ‘navel’ and the bodily ingredients (dhātu) are the ‘lungs’. According to the Vajraḍākavivṛti, the districts Kulatā, Maru, Pretapurī and Triśakuni are associated with the family deity of Vārāhī; while in the Abhidhānottarottaratantra there is the Ḍāka deity named Ratnaḍāka standing in the center of the districts named Kāmarūpa, Triśakuni, Oḍra and Kosala.

[...] (3) Kāmarūpa, Oḍra, Triśakuna (for Triśakuni), and Kauśala are the kṣetra [sites]. (4) The upakṣetra [sites] are Kaliṅga, Lampāka, Kāñcī, and Himālaya.

Triśakuni (त्रिशकुनि) refers to one of the Twenty-four Great Sacred Places (Tibetan: gnas chen nyer bzhi) according to the Cakrasaṃvaratantra (Chakrasamvara Tantra).—In the Nyingma tradition, Jigme Lingpa’s Yumka Dechen Gyalmo has incorporated this enumeration. Furthermore, Jigme Lingpa says that “as regards these places, they are entirely present internally, within our own body”.—For example, “the navel is Triśakuni”.—This correlation can also be found in the Sampuṭodbhavatantra (“Emergence from Samputa Tantra”) [e.g., “The navel is thought to be Triśakuni. Kośala is the tip of the nose. These last two are called auxiliary kṣetras”]
