The Buddha’s teachings offers the most satisfactory explanation of where man came from and where he is going. When we die, the mind, with all the tendencies, preferences, abilities and characteristics that have been developed and conditioned in this life, re-establishes itself in a new being.
Thus the new individual grows and develops a personality conditioned both by the mental characteristics that have been carried over from the previous life and by the new environment. The personality will change and be modified by conscious effort and conditioning factors like education, parental influence and society but once again at death, it will re-establish itself as life in a new being. This process of dying and being reborn will continue until the conditions that cause it, the mental factors of craving and ignorance, cease. When they do, instead of being reborn, the mind attains a state called Nirvana.
