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.

Whoever is able to do so will dispel their pain and find lasting happiness in their heart.

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.
