Lama Ole’s answer:
We can examine the level on which the joy takes place. If it consists of having something and stops the moment we don’t have it anymore, then the joy is constricting and unpleasant.
Actually, we can enjoy everything as long as we don’t have a problem once it’s gone. If the pleasure becomes strong enough, then it breaks the limits of the ego. One can enter it via the ego and discover something that is a thousand times greater than anything one has ever known before. As long as it doesn’t dominate us, we can enjoy it fearlessly. As an old master once said, “Since everything is a play of mind anyway, we may as well enjoy it.” What he was talking about is life itself.
