The one controller of the many inactive ones, who makes the single seed manifold — the wise who behold him dwelling within themselves, to them belongs eternal happiness, and to no others.
The root cause of a person's suffering is their pride. Even if someone makes a sacrifice, they can still get caught up in their own pride. What is the point of such a sacrifice? It is pride, or ego, that should be sacrificed. That is where true happiness and bliss are found.
True happiness requires more than just knowledge; it demands love. The love of God can only fill a person's heart after it has been purified of worldly desires, and this purification can only be achieved through self-discipline and detachment.
