Yamasis: Why don't more people become spiritual? Because they are swept away by this, a continuous drive for acquisition and preservation of worldly things. And spiritual life requires that maturity which will enable you to make a deliberate choice. I want to be enlightened. What buddha wanted, what weve garanda wanted, rama khrishna wanted,. All the great saints and mystics wanted all across history, in all traditions. It's entirely possible but you have to make the choice. Very few do.
Swami Sarvapriyananda teaches the Katha Upanishad, which is one of the most popular Upanishads. The scripture concerns the story of a young man who goes to the house of death to find out what happens after death. The reply describes the nature of reality and the meaning of life.
