“This is a wrong attitude that has been given to you—that sadness is wrong. Nothing is wrong with it. It is another polarity of life.
Happiness is one pole, sadness is another. Blissfulness is one pole, misery is another. Life consists of both, and life is richer because of both.
A life only of blissfulness will have extension, but will not have depth. A life of only sadness, will have depth, but will not have extension. A life of both sadness and blissfulness is multi-dimensional; it moves in all dimensions together.
To me, life in its totality is good. And when you understand life in its totality, only then can you celebrate; otherwise not. Celebration means: whatsoever happens is irrelevant—I will celebrate. Celebration is not conditional on certain things: “When I am happy then I will celebrate”, or “When I am unhappy I will not celebrate”.
Celebration is unconditional; I celebrate life. It brings unhappiness—good, I celebrate it. It brings happiness—good, I celebrate it. Celebration is my attitude, unconditional to what life brings.”
