Every human being has four birthdays.
The first is when he emerges from his mother's womb and, being neither holy nor unholy, craves only for food and shelter;
the second Is when he begins his spiritual study to lead him from darkness to light;
the third is when he has gained wisdom, having mastered the disciplines propounded by the rishis for achieving self-realisation;
the fourth and last is when he realises his true identity and merges with Brahman.
