The only thing you must remember is how fortunate you are.
When you forget this you become sad. Sorrow indicates your negative qualities, and your attachment to your positive qualities. When you think you are too good, you blame the world; then you become sad. The purpose of sorrow is to bring you back to the self. And self is all Joy. But this is possible only through Knowledge and awareness.
Knowledge or awareness leads sorrow towards the self. With lack of Knowledge, the same sorrow multiplies and does not get completed. Knowledge completes sorrow.
In this path you have everything. We have this beautiful Knowledge which has all the flavors in it – wisdom, laughter, seva, silence, singing, dancing, humor, celebration, yagyas, caring, complaints, problems, complications, and chaos to add color.
Life is so colorful!
