That happiness is called good, in which one is pleased after repetition (of enjoyment), and reaches the close of all misery, which is like poison first and comparable to nectar in the long run, and which is produced from a clear knowledge of the self.  That happiness is called passionate, which (flows) from contact between the senses and their objects, and which is at first comparable to nectar and in the long run like poison. That happiness is described as dark, which arises from sleep, laziness, heedlessness, which deludes the self, both at first and in its consequences.
