So being pleasant in the body is generally referred to as health and pleasure. When you feel pleasant in your mind we call it peace and joy. When you feel pleasant in your emotions we call it love and compassion. When you feel pleasant in your energies we call it blissfulness and ecstasy. If these things happen within you to whatever extent possible you feel well.
