Usually what I do after shuffling is divide the deck into three piles, with my right hand. Then hold my left hand over each pile (about one inch above it) to feel which pile is giving off the most energy and/or heat. Then that pile goes on top, with the other two piles on the bottom. And I pull the cards from the top of the deck at that point.
I have tried other things on occasion, and everything I have tried has worked. I just think when we sincerely seek answers, the right cards come to us, no matter how we do it.
I have also tried things like holding the deck in my hand (face down) and letting a number come to mind. It has to be a number no higher than the number of cards in the deck. Let's say I hear a 12 in my mind. Then I just count of 12 cards, and the 12th card is the one.
I have even thrown the cards up in the air and chosen the ones that landed closest to me.
Or spread them all around me, and put some music one and closed my eyes till the end of the song, swaying to the music as I sat there, and till I forgot how the cards were layed out. Then at the end, still with my eyes closed, picked cards at random where my hand felt impelled to go.
It just always works!
Honestly, I have never not gotten the right cards no matter what I do.
