Cause and Effect...

The universe is like a dome; it vibrates to that which you say in it, and answers the same back to you; so also is the law of action we reap what we sow.

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

Every thing and being on the surface of existence seem separate from one another, but in every plane beneath the surface they approach nearer to each other, and in the innermost plane they all become one. Every disturbance therefore, caused to the peace of the smallest part of existence on the surface, inwardly affects the soul. Thus any thought, speech or action that disturbs peace is wrong, evil, and a sin; if it brings about peace it is right, good, and a virtue. Life being like a dome, its nature is also dome-like. Disturbance of the slightest part of life disturbs the whole and returns as a curse upon the person who caused it; any peace produced on the surface comforts the whole, and thence returns as peace to the producer.

Man forms his future by his actions. His every good or bad action spreads its vibrations and becomes known throughout the universe. The more spiritual a man is, the stronger and clearer are the vibrations of his actions, which spread over the world and weave his future. The universe is like a dome: it vibrates to that which you say in it, and echoes the same back to you. So also is the law of action: we reap what we sow.

The picture itself inspires the painter. As it progresses he sees that in a certain place there ought to be a different color. This is not right; that is not right, and so on. And as he looks at the picture, he sees its faults, and so he alters it here and there. So it is with each life. ... As we sow, so we reap. All that we do, we see in its reaction, and the reaction changes our life. The painter sees he must finish the picture differently, and so our actions tell us whether we ought to act differently.
