Basically, there can only be two answers. One is to overcome separateness and find unity by regression to the state of unity which existed before awareness ever arose, that is, before man was born. The other answer is to be fully born, to develop one's awareness, one's reason, one's capacity to love to such a point that one transcends one's own egocentric involvement, and arrives at a new harmony, at a new oneness with the world.
The affirmation of one's own life, happiness, growth and freedom, is rooted in one's capacity to love.
Most people see the problem of love primarily as that of being loved, rather than that of loving, of one's capacity to love. Hence the problem to them is how to be loved, how to be lovable.
