What is the use of worshipping the Gods?

Mai. -   "Of what use is it? you have worshipped the Gods:

           What have they done for you; it is labour in vain,

            to bestow upon them adoration.

Char. -  Speak not profanely.

"It is our duty -- and the Gods

Undoubtedly are pleased with what is offered

In lowliness of spirit, and with reference,

In thought, and deed, and pious self-denial:

Go therefore and present the offering."

"Go you to where the four roads meet, and there present it to the Great Mothers.

The Great Mother = The Matri.

The Matri is the personified energy of a divinity, and in a figurative sense the mother of gods and men; the Matris are usually reckoned seven or eight, but in one enumeration they are made sixteen. The presentation of oblations to them as a regular and permanent rite is no longer known in Gangetic India. Tantrika ceremonies addressed to the sixteeen Matris are not uncommon, but the rite in the text appear to be a matter of course, and seems to take the place of that enjoined by Menu to the Pitris, the manes or progenitors.  "Turning to the South let him present all the residue of his oblation to the Pitris."
