Start acting spontaneously. It will be difficult in the beginning, you will feel much discomfort. With a premeditated answer there is less discomfort, you are more certain. Why are we not spontaneous? It is because of fear, the fear that the answer may be wrong. It's better to decide beforehand then you can be certain; but certainty always belongs to death.
Remember, life is always uncertain. Everything dead is certain, life is always uncertain. Everything dead is solid, fixed – its nature cannot be changed; everything alive is moving, changing – a flow, a liquid thing, flexible, able to move in any direction. The more you become certain, the more you will miss life. And those who know, know life is God. If you miss life, you miss God.
Act spontaneously. If there is discomfort in the beginning allow it to be there; don't hide it and don't suppress it – and don't imitate. Be childlike but don't be childish. If you are childlike, you will become a great saint; if you are childish, you will become a great, knowledgeable person.
