"Your mind has enormous hidden dimensions. Open yourselves completely to whatever reactions and emotions the world evokes from time to time. Accept them all without any reservation or resentment. By assimilating everything and all, your mind grows deeper, stabler and more enriched."
The Guiding force of Narayanashrama Tapovanam & Center for Inner Resources Development
