Sri Chinmoy: It is something different. When you hear a piece of music, you are temporarily transported to a realm of ecstasy. Then, after five or ten minutes, the music goes away and the joy disappears. When you make something, you experience the joy of creation. You are in ecstasy for fifteen minutes or half an hour, or for a day or two. Then your joy vanishes. Why? Because the joy that you get from your creation or from somebody else's creation is limited by the capacity of that creation. Your creation may have the capacity to give joy for five or ten minutes. Then it stops. This is because you have not created something infinite or eternal. But when you have meditated for fifteen or twenty years, eight or ten hours a day, you will have a free access to something boundless, infinite.
When you meditate, you enter into the Vast — the vast sea, or the vast sky, or infinite Light. When you enter into the Vast, you become, by God's Grace, a channel which flows endlessly, like the Ganges flowing down from the Himalayas. So when you meditate, you get a continuous flow of inner joy. The joy which you get from some earthly creation lasts for a short time, because both the creator and the creation are bound. But by meditating, you enter into boundlessness. Then your joy is really spontaneous and permanent.
When a spiritual Master says that he has inner Peace, inner Joy, inner Bliss, he has these permanently. They flow constantly from within because he has grown into the Source. This Joy is infinitely greater and more fulfilling than the fleeting joy which an ordinary human being may experience.
