If my love is without sacrifice, it is selfish. Such a love is barter, for there is exchange of love and devotion in return for something. It is conditional love.
Dada VaswaniHappiness, true happiness, is an inner quality. It is a state of mind. If your mind is at peace, you are happy. If your mind is at peace, but you have nothing else, you can be happy. If you have everything the world can give - pleasure, possessions, power - but lack peace of mind, you can never be happy.
