Cause and effect are not two different things. The effect of today will be the cause of tomorrow. There is no cause, isolated, which produces an effect; they are interrelated. There is no such thing as a law of cause and effect, which means that there is really no such thing as what we call karma. To us, karma means a result with a previous cause, but in the interval between the effect and the cause there has been time. In that time there has been a tremendous lot of change and therefore the effect is never the same. And the effect is going to produce another cause which will never be merely the result of the effect. Do not say, -I do not believe in karma- that is not the point at all. Karma means, very simply, action and the result, with its further cause. Sow a mango seed and it is bound to produce a mango tree-but the human mind is not like that. The human mind is capable of transformation within itself, immediate comprehension, which is a breaking away from the cause, always.
