Meditation practice is a mind exercise to detach from thought processes, and the goal is to realize reality as it is without interpretation by mental concepts. In other words, it is going beyond concepts, beyond words, to realize THAT reality which the words are meant to represent. Praying to or praise of God is a valid religious practice, as is chanting, but in still mind meditation, eventually the words are displaced by THAT which the words are meant to address. In this state of mind, there is no thought, and thus no "I" arises to interpret what is realized.
What is the non verbal reality represented by the word God? No one can say, for if the mind is free from concepts, there are no words, if there are words, then the non verbal reality was not realized.
