Cause and Effect...

He who has spent has used; he who has collected has lost; but he who has given has saved his treasure forever.

Bowl of Saki, by Hazrat Inayat Khan
Commentary by Pir-o-Murshid Inayat Khan:

The tendency to doubt, to be depressed, the tendency towards fear, suspicion and confusion, the tendency to puzzle -- where does it all come from? It all comes from the thought of getting something in return: 'will another give me back what I have given him? Shall I get the just portion back, or less?' if that is the thought behind one's acts there will be fear, doubt, suspicion, puzzle and confusion. For what is doubt? Doubt is a cloud that stands before the sun, keeping it from shining its light. So is doubt: gathering around the soul it keeps its light from shining out, and man becomes confused and perplexed. Once selflessness is developed, it breaks through the cloud saying, 'What do I care whether anyone appreciates it; I only know to give my service, and that is all my satisfaction. I do not look forward to get it back. I have given and it is finished; this is where my duty ends.' That person is blessed, because he has conquered, he has won.

Then it is lack of knowledge of the divine justice when man doubts whether he will get his just portion, or whether the other will get the best of him. If he looked up and saw the perfect Judge, God Himself, whose justice is so great that in the end the portions are made equal and even -- there is only a question about the beginning, not about the end -- if only he saw the justice of God, he would become brave, he would trust and not trouble about a return. God is responsible for returning a thousandfold what man has ever given.

The mystic can see from the point of view of everyone else, as well as from his own, which may be quite the contrary. For instance, in his teachings, Christ says, 'If anyone asks you for your coat, give him your overcoat, also.' A worldly man will say, 'It is not practical; if someone asked this of me every day, I would be continually buying new coats!' Yet, at the same time, it is more than practical from the point of view of the Master. For, according to his view, we cannot give anything, in whatever form, without getting it back in some way or other. Pure thought, good will, our service, our time, whatever we give, is never lost. It comes back to us according to our willingness to give, it comes back to us a thousandfold. That is why one is never the loser by being generous; one only gains.

The mystic sees the law in all things, and this gives him an insight into life. He begins to see why this misery has come upon him, why that pleasure has come; why one person is prospering and another not, why one is progressing and not another. All these things become clear to him because he sees the law working in all things. The law of the mystic is not the law of the people. It is the law of nature; it is the real law.
