We can see the same spirit in everybody only when we know we are that spirit, Atman or Self. Only a person who has understood his own Self can see that Self in everybody.
Swami SatchidanandaThere is one Cosmic Essence, all-pervading, all-knowing, all-powerful. This nameless formless essence can be approached by any name, any form, any symbol that suites the taste of the individual. Follow your religion, but try to understand the real purpose behind all of the rituals and traditions, and experience that Oneness.
