When you take a body it is to make progress and when you leave it the period of progress is over.
And true progress is sadhana; that is, it is the most conscious and swiftest progress. Otherwise one makes progress with the rhythm of Nature, which means that it can take centuries and centuries and centuries and millenniums to make the slightest bit of progress. But true progress is that made by sadhana. In yoga one can do in a very short time what takes otherwise an interminable time. But it is always in the body and always upon earth that it is done, not elsewhere. That is why when one is in a body one must take advantage of it and not waste one's time, and not say: "A little later, a little later." It is much better to do it immediately. All the years you pass without making any progress are wasted, which you are sure to regret afterwards.
