Dear Parag,
You can reach him at 626-451-0305 or duf@earthlink.net The workshops were in California - check out his schedule on his website
www.sanskritmantra.com for future pujas he has planned. If I were you, I would only try one mantra at a time. It's better to focus your energy on one goal at a time. From what I remember in his workshops, he said you can do more than one mantra at a time - if it's on a related topic. So you could do several on abundance, prosperity, security - but you wouldn't add, say, relationships to the mix.
If you're needing guidance on how to proceed with a particular goal - I would definitely focus on your sixth chakra or third eye for guidance. There is a mudra in Sabrina's book specifically for receiving spiritual guidance. Hope that helps.
Rachel
