The Buddha said: Five hundred glances in a past life earn you one chance encounter in this life. Five hundred chance encounters in a past life earn you one meeting in this life. Five hundred meetings in a past life earn you one acquaintance in this life. Five hundred acquaintances in a past life earn you one understanding in this life. Five hundred understandings in a past life earn you one love in this life.
