Translation
At the sides of the hexagon (of Vartālī’s yantra) the pair Stambhinī (and) Krodhinī should be worshipped. The first (holds) a pestle in (her) hand and (makes) the wish (-granting gesture); the other (i.e., Krodhinī) holds a skull and a plough. In the apex of the hexagon one should worship Caṇḍoccaṇḍa, her (i.e., Vartālī’s) best son, who holds with (his) hands a trident, a snake, a rattle drum and a skull, is the colour of a sapphire, naked (and) shines with a large quantity of matted hair.
Attributes:
Stambhinī: R wish-granting gesture; L pestle
Krodhinī: R skull; L plough
Caṇḍoccaṇḍa: R rattle drum, skull; L snake, trident
Remarks:
The three deities described here surround Vārtālī in her yantra: Stambhinī, “the immobilizing one.” is at her right side, Krodhinī, “the angry one,” is at her left, and Caṇḍoccaṇḍa is at the apex of the yantra. The word Caṇḍoccaṇḍa may incorporate the names of two originally separate deities, Caṇḍa, “fierce,” and Uccaṇḍa, “very fierce,” comparable to Caṇḍa and Pracaṇḍa, the pair of guardians at Vaisnava shrines. The two goddesses carry three of Vārtālī’s attributes, the pair of agricultural symbols, the pestle - the plough, and make the wish-granting gesture, while Caṇḍoccaṇḍa holds Śiva's characteristic attributes. Mahīdhara’s commentary assigns the rattle drum and the skull to his right hands and the trident and the snake to Caṇḍoccaṇḍa's left hands. Since the rattle drum - the snake and the skull - the trident form pairs, I have listed them accordingly. A similar description appears in Dakṣiṇāmūrti-Saṃhitā 37.33-35 (quoted in ŚVT 2, p. 386, 13-15). The three deities are also worshipped in the Vārāhī/Daṇḍinī pūjā prescribed in the Nityotsava, p. 141, 9-15 by the Maharashtrian Umānandanātha (or, Jagannātha Paṇḍita), a text written in 1745.
