The attachment and love and affection of man are not very different from the attachment of the birds and animals. There is a time when the sparrow looks after its young and brings grains in its beak and puts them into the beak of its young ones, and they anxiously await the coming of their mother. And this goes on until their wings are grown, and once the young ones have known the branches of the tree and they have flown in the forests under the protection of their mother, they never again remember that mother who was so kind to them. There are moments of emotion, there are impulses of love, of attachment, of affection, but there comes a time when these pass; they pale and fade away. And there comes a time when a person thinks that there is something else he desires and something else he would like to love.
