tasya tāvadvidhiṃ vakṣye purāṇaśrutibhāṣitam

The knowers of the Purâṇas and Śrutis have described the planetary offerings as being of three kinds, viz.—1. of the thousand homas (fire oblations); 2. of a lac or a hundred thousand homas; 3. of ten millions of homas, that fulfil all desires. Hear the ways of performing the homa with a thousand offerings, as told in the Purâṇas. This is called Navagraha yajña, or the sacrifice to the Nine Planets. An altar, measuring two vitasti wide, within the sacrificial pond, should be made in the direction of north-east of the fire pit.—5-7.
