Here the different opinions are described. Some, the yogis, who cover up (vasana) the difference (vikalpa), say the soul, master of the self, gives happiness and suffering. The Gita (6.5) says atmaiva hy atmano bandhur atmaiva ripur atmana: the atma itself is the friend of the soul and the enemy of the soul. Or the meaning can be: some, the advaitins, who say that the jiva and the lord become one say that the atma is the source of happiness and suffering. They also say that devatas cannot be the cause since they are controlled by karma as well, and karma cannot be the cause because it is not independent. Thus only the atma is the cause and nothing else. Others, those who believe in planets controlled by devatas, say that planets are the cause. The Mimamsakas say that karma is the cause. Others, the Lokayatas, say that svabhava, the inherent property of matter, is the cause.
