Realization is the result of the three other grades. In the third kind of experience man pursued meditation; but in this, meditation pursues man. In other words, it is no longer the singer who sings the song, but the song sings the singer. This fourth grade is a kind of expansion of consciousness; it is the unfoldment of the soul; it is diving deep within oneself; it is communicating with each atom of life existing in the whole world; it is realizing the real "I" in which is the fulfillment of life's purpose.
