In the beginning, compassion is like the seed without which we cannot have any fruit; in the middle, compassion is like water to nourish the see we have planted; in the end, compassion is like the warmth of the sun that brings the fruit to ripening.
And could I look upon her without compassion, seeing her punishment in the ruin she was, in her profound unfitness for this earth on which she was placed, in the vanity of sorrow which had become a master mania, like the vanity of penitence, the vanity of remorse, the vanity of unworthiness, and other monstrous vanities that have been curses in this world?
If one doth act in friendly wise, With no evil thought toward any single creature, And in so doing becometh proper, And if he have compassion in his soul Toward all living beings--this noble one Doth acquire abundant Virtue.
Ultimately, the reason why love and compassion bring the greatest happiness is simply that our nature cherishes them above all else. The need for love lies at the very foundation of human existence.
