Like in Hinduism, is there any teaching on the stages of life in Buddhism ?
P.S. Answers for this question will be great "Dhamma gifts" for my upcoming Birth day.
There really isn't anything quite like ashrama in Buddhism, at least as it applies to an individual person's life. Buddhism takes a simple view that one is born, lives, and then dies, within a cycle of saṃsāra (a belief shared with Hinduism). Within the context of that life, one is either awakened or one isn't.
I think it's interesting, since Buddhism defines many other "stages" involving aspects of life (just not about life itself):
