Life is multidimensional. Don't confine it, don't make it linear, don't live like a line. Live the multidimensions of it, the multi-phases of it, and then you cannot be consistent, because life is paradoxical -- one moment it is joy, another moment it is sadness. If you are very consistent, then you have to go on smiling; whether your heart is crying or smiling, that doesn't matter, you have to be consistent...
Life consists of sadness too. And sadness is also beautiful; it has its own depth, its own delicacy, its own deliciousness, its own taste. A man is poorer if he has not known sadness; he is impoverished, very much impoverished. His laughter will be shallow, his laughter will not have depth, because depth comes only through sadness. A man who knows sadness, if he laughs, his laughter will have depth. His laughter will have something of his sadness too, his laughter will be more colorful.
A man who lives life in its totality is a rainbow; he lives the whole spectrum of it. He cannot be consistent, he has to be inconsistent.
