When you chant AUM, try to feel that it is God who is climbing up and down within you. Hundreds of seekers in India have realised God simply by repeating AUM. AUM is the symbol of God, the Creator.
On which aspect did you want me to speak about AUM?
Questioner: This is the answer I wanted.
Sri Chinmoy: One can speak and write for hours about AUM. The main thing, my personal feeling, is that when you repeat AUM, please try to observe what actually happens. If you repeat the name of a cat, a dog or a monkey, or even of an ordinary person, you get no inspiration. But when you utter AUM which is the symbol of the Creator, the life-breath of the Creator, you immediately get an inner feeling, the feeling that inspires your inner and outer movements to enlarge your vision and fulfil your life here on earth. This is the secret of AUM. If you want to cherish a secret all your life, then here is the secret. Please chant AUM and everything is yours.From:Sri Chinmoy,AUM — Vol. 2, No. 3, 27 October 1966, Boro Park Printers -- Brooklyn, N. Y, 1966
