Guruji is talking about Ashtavakhra Gita in the Ashram and here are a few quotes:
Happiness is when wanting ends and giving or sharing begins
Santosh or contentment is a niyama, a rule for spirituality … No one can take it from you if you deeply decide you are going to have it!!
Contentment gives Happiness. You can be unhappy even in the best of situations if you are not content.
“Antarmukhi Sada Sukhi” dweller in the self is always in bliss. Even these words have the power to give relief.
