Albean: If i am looking for my real nature, which is infinite existence, consciousness, bliss, that i am one with god, and that is where i will find find lasting, a bliss, a profound satisfaction. That is spiritual life. The two cannot be combined, because one is of the nature of maa, of error, of falsity. One may have a lot of power and be very powerful and very rich, or one may be a fakiin absolutely penniless, with not a single possession. But one will be completely satisfied and full if one has realized that ultimate nature of ourselves, of the of this existence.
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.
