One of my favorite meditations is a form of self-inquiry. Near as I can tell, it was positied by Ramana Maharsi to folks like Yogananda and Brunton, and consists mainly of turning the attention inward, and asking, "Who am I, really?".
Ideas will come and go...you just allow them to enter the realm of awareness, without judgement, and acknowledge that each emerging idea is a part of your Self, but not a total answer. Acknowledge the idea, then push it to the side a bit (so to speak) to look deeper past it, and inquire again, deeper still..."That may be part of who I am, but not all that I am. Who am I, really?".
You need to be willing to sit with responses sent up from the deep mind that may have been material you previously defended against (tried to push out of mind, rather than ponder and think about, much less embrace as part of You). If you stay with this approach, you should eventually reach a point where the part of you who knows steps forward in introduction, and you get to meet the Mystic Mind within each and all.
Will it change you into a Buddhist saint, or Hindi Sage? Nope. You'll still be who you are. But you will hopefully have had a brief interaction with the Divine within, which has a net effect of changing the overall colors of glass one percieces life through. Basically, thins the veil so that the potentcy of Spirit is closer to consciousness. Or so they tell me.
Bon Chance!
