The condition of your brain waves at the time of your deep sleep is called Delta Frequency. When you bring this frequency consciously during your wakeful stage is Delta Frequency Meditation. Meditation is concentrating on the gap between your thoughts (which is actually the talk of your mind), and widening it as far as possible to the extent of no thought happening. Once you reached this stage, you get connected to your Supreme Source (God). How do you know He is your Source? From the beam of rays that you receive in different colors—each one representing different qualities which finds perfect synchronization with the very being of our inner essence. For example, when you receive red colored rays, you feel empowered, orange (purifying effect), yellow (joyful feeling), green (loveful feeling), blue (peaceful), indigo (wisdom), violet (balance/bliss). These qualities are benevolent and beneficent in nature, hence originate from God. And the moment you mention about any of your personal need, you lose the connection! From my meditation, what I have understood is that God hates to hear prayer in contrast to the much-publicized statement that God is a God of prayer! Continuing in this Delta Frequency gives you an extraordinary physical pleasure too [bonus] which is not comparable to anything you have known in your life. That is why people like Jesus spent the whole night being connected with God. (Mark 1:35; John 8:1, 2)
