Yea I was asking about this earlier myself, and I was posting about it in the Tantra section. The pujas are quite a bit of stuff, although I figure that might be where the adaptation can come in. However, the information on contacting Hindu deities themselves is a bit out there, and it can be hard to come by. Hindu spiritualism is also rife with a lot of charlatan activity, folks trying to make bucks on gullibility.
My suggestion, as this is what I am currently doing right now, would be to first try to open channels with a consistent meditation on Yantra with an appropriate mantra for what type of relationship you are trying to convey. I wouldn’t attempt to try to make any explicit requests yet, but would rather focus on establishing a basis for open communication. From there, as you are training skills like psychic sight, astral travel, and lucid dreaming, you might want to contact them there, and ask them how you might best be able to perform this work according to your situation.
