Swami Vivekanada.

 "Therefore, to gain this infinite universal individuality, this miserable little prison - individuality must go. Then alone can death cease when I am one with life, then alone can misery cease when I am one with happiness itself, then alone can all errors cease when I am one with knowledge itself; and this is the necessary scientific conclusion- Science has proved to me that physical individuality is a delusion, that really my body is one little continuously changing body in an unbroken ocean of matter, and Advaita (unity) is the necessary conclusion with my other counterpart, Soul."
