Do you believe in reincarnation?

Yes.

The Bhagavad-gita, the principal scripture of the Hare Krishna movement, and the roots of understanding reincarnation, states “As the embodied soul continually passes, in this body, from boyhood to youth to old age, the soul similarly passes into another body at death. The self-realized soul is not bewildered by such a change.”

The Vedas further explain that the soul in the material world transmigrates within a cycle of material birth and death through 8,400,000 forms of life. The human form, however, is the only birth which affords one the chance for spiritual realization. Species lower than humans are not endowed with sufficient intelligence to understand the soul as different from the body.
