As you have to curdle the milk and after a day you have to seperate butter by running it in mixie with a butter seperator. Likewise God is not visible to our naked eye. Intense meditation within and disengaging the mind will lead to realisation. This philosophy is found in Hindu, Buddha, zen and other treditions. Those who practiced and found perfection like Shri Ramakrishna, Shri Vivekananda, Paramahamsa Yogananda and His preceptors have recorded their experiences. Do you agree the philosophy?
