The Knowledge of the Oneness of Brahman leads you to the highest bliss. Identity of the Brahman is not possible if you view them along with their upadhis or add-ons. Eliminate the upadhis, and you find the Reality.
The one who attains Reality does not suffer from any wants. The Almighty Sadguru looks after his welfare personally. Bliss of the Self and Liberation are possible only through the teachings of the Sadguru.
If you want to see God, come completely disarmed. This means – If you want to see God, drop all your pride and surrender yourself to God. Surrender yourself completely to God.
A realized person may continue ordinary worldly activity, yet inwardly remains free from ego, attachment and duality, established in the natural state.
