Did the Persians believe in life after death?

The Persian Empire included many religions. Most had no concept of life after death, being centred on daily life.

Those who sought a life after death became members of mystery cults, but entry to these was costly and operated at cult centres which few people could afford to access, in both money and travel barriers.

Some mystery cults began to travel to the customers and so more could join in. They included the mystery cults of Mithra, Jesus, Isis, Osiris etc. The Jesus cult (now Christianity) was particularly successful as it travelled to all countries, was cheap and even women and slaves could join.
