All religious superstitions are vain imaginations. ... This society, that I see you before me, and [that] I am talking to you — this is all superstition; all must be given up. Just see what it takes to become a philosopher! This is the [path] of [Jnâna-] Yoga, the way through knowledge. The other [paths] are easy, slow, ... but th...is is pure strength of mind. No weakling [can follow this path of knowledge. You must be able to say:] "I am the Soul, the ever free; [I] never was bound. Time is in me, not I in time. God was born in my mind. God the Father, Father of the universe — he is created by me in my own mind...."
Do you call yourselves philosophers? Show it! Think of this, talk [of] this, and [help] each other in this path, and give up all superstition!
