How to develop psychic powers

I feel that psychic powers including intuition can be developed only with God's Grace and blessings.The following techniques are helpful.
1.Gazing at the photo or symbolic representation of your God, Guru or spiritual guide.
2.Listening to spiritual,meditational music. Some of the music based on brain waves and other technologies is very effective in opening up psychic powers and abilities.
3.Expressing constant gratitude and living in complete surrender to the Divine.
