One of the gurus in Mind Power and Meditations Deepak Chopra gives simple tips of knowing GOD, if there's really GOD who creates everything in the Universe.

This is part of the bedtime Shema, the prayers and meditations before sleep, found in the Siddur after the evening service, Maariv. One of the most ancient names of G-d is "El" - and we see that name in the names of the angels. The first angel is Michael - like G-D - right side. The second angel is Gavriel - the Gevurah, power of G-d - left side. The third angel is Uriel - the Or - light of G-d - in front. The fourth angel is Rafael - healed by G-d - following. The fifth angel is Shekhinat El - the Shekhina - feminine presence of G-d - above the head. The breathing sounds are reminders to take deep, full breaths as you do the meditation, through the nose, holding slightly as feels comfortable. This meditation brings great protection and comfort, and can be used as a mantra anywhere, anytime.
