When you move amidst the world of sense, free from attachment and aversion alike, there comes the peace in which all sorrows end, and you live in the wisdom of the Self.
– Bhagavad Gita
If we do not realize the unity of life, God will let us suffer until we are forced to change our ways.
Of course, it’s often difficult and painful to change.
We should never conclude that our lives are hopeless, that we can never improve, that we are condemned by God or fate or chemistry or conditioning to repeat the same mistakes. We can always choose a better path, someday we will.
