What DOES "life cycle" mean. The cycle of life of a specific species. For example, the life cycle of a frog is, it starts off as an egg, it hatches as a tadpole, it grows back legs, it grows front legs, it moves onto land, it loses its tail, it lays eggs. Repeat. Do an image search.
According to Hinduism life and death is cycle. There is life after death & death after life. This theory in Hinduism is called Reincarnation (punarjanma).
