There are many method of meditation, but here I will show you one that is easy and reliable. The key to any psychic/spiritual development is the subconscious mind, with access to the subconscious you have access to all the wonders of spirit, past lives and much more. The method below will help you to gain access to your subconscious.
First find a candle and light it, make sure it's in a safe place where it where won't fall over and away from curtains. Make sure it's just above eye level from where you will be sitting or laying. Next get yourself comfortable preferably in a place where you can relax and won't be disturbed. If you wish to use incense then that's fine, but it's not really necessary, as with all methods it's personal preference, whatever your comfortable with and what you feel is right for you.
When you get comfortable, focus your eyes on the candle flame, while watching the flame, notice your breathing, the rise and fall of your breathing, find a steady pattern. Next on every in breath count backwards from 100 and on every out breath say " I fully expand my subconscious awareness" or something to that effect. So on every in breath count backwards and every out breath say, " I fully expand my subconscious awareness"
