It is inaccurate to consider reincarnation as a false aspect. The Punarbhavaya or the reincarnation is not a false aspect. It is a truth, and there is a way to confirm this truth by practicing Buddhism. We need to practice meditation and attain the fourth state of concentration (Dhyana) in which the meditator will have the ability to check upon his past lives. Then, you will be able to see your past lives and confirm the reincarnation.
