In simple words the truth is, neither love nor hate, rather truth; which is compassion! but for a person, limited as we are, tender as we are, sensitive as we are, vulnerable as we are, fearful as we are, scared of criticism as we are, to get to the state of compassion; in other words, to on one hand not judge others and on the other, to actively help people, we must begin life with unconditional love, develop self-discipline (which usually must come through harsh criticism, for a person by nature is not disciplined, for the state of love, is an open loose undisciplined state) and eventually give up our resentment and come back to compassion!
