When you are hungry, only one thought that of food is there. When food goes inside the body and the processing starts, brain becomes ready for its function, that is, thoughts start generating. Including the thought of 'you', God, soul, creation and so on. Thoughts arise because of life energy. Thought is entrapped in likes and dislikes. It loses contact with the energy from where it draws its sustenance. The secret, the origin is in this energy and not what thoughts depict.
