All happiness comes from awareness. The more we are conscious the deeper the joy. Acceptance of pain, non-resistance, courage and endurance - these open deep and perennial sources of real happiness, true bliss.
The essence of saintliness is total acceptance of the present moment, harmony with things as they happen.
By being with yourself, the 'I am', by watching yourself in your daily life with alert interest, with the intention to understand rather than judge, in full acceptance of whatever may emerge, because it is there, you encourage the deep to come to the surface, and enrich your life and consciousness with its captive energies.
The first steps in self-acceptance are not at all pleasant, for what one sees is not a happy sight. One needs all the courage to go further.
