The easiest way to get to alpha state, for me, is to sit back, relax my muscles, breathe deeply and slowly, and count from 10 to 1 (with each number I feel myself getting lighter more relaxed).
That's Silva method. He recommends to count from 100 to 1 when starting, but takes too long and most of the time I fall asleep. But you can try what suits you the best (50, 20, 5, whatever).
Don't push yourself to alpha, but let go and 'fall' into it. You won't feel any 'special' sensation, but you will feel different; better, peacefull, GOOD! Just like anything else, the more you do it the easier it gets.
