Each person has his/her own soul (a part of God, and this part is beyond time and space, )which means that we are spiritual beings. The meaning of our life lies in continual spiritual development, which will free our souls from the cycle of reincarnation and finally awaken us to our true nature as complete spiritual beings.
Only then can a man can come back to the earth out of pure love, to help his fellow human beings. The difference between an ordinary human and an enlightened being is following: an ordinary human is like a man in a prison and Bodhisattva* is someone, who has the key to get out of this prison.
There is a power inside of us and also around us, which we perceive as a negative material force. This force causes us sorrows, fears and suffering and we feel it inside ourselves.
Everyone has this force within them which springs from matter and it is called cacodaemon
. Conversely, every human being also has an agathodaemon
(noble spirit) within them, the power, which comes from our positive human nature and the soul. (see also five inner voices
* A Bodhisattva is a being who reached the highest level of perfection and enlightenment, and who came out of Nirvana, who has the will and ability to immerse in it again, but refuses to do so out of Love and compassion and a desire to help them attain perfection. Bodhisattvas come back to Earth by choice to help humanity in their evolution.
