In the Laksmi Puja there doesn’t seem to be the nectar bath offering. Why?
All the offerings are in the Cosmic Puja. I didn’t want to keep cutting and pasting from one book to another, so I gave the shell of the puja, and you can supplement as per your desire.
You have translated Śrīṃ as Increase. Can you help me understand what it increases?
Anything you want. Actually śa means peace; r means your mind; ī means your intuition; ṃ means perfection. That which brings your mind and intuition to perfection (increase) is Śrīṃ. It is the bīja mantra of Lakṣmī.
