This is one of my favorite quotes. I think it relates to "Contagion and Magic":
"Love is essentially self-communicative; those who do not have it catch it from those who have it. Those who receive love from others cannot be its recipients without giving a response that, in itself, is the nature of love" (Meher Baba, 1973, p. 8-9).

All the best,
