Garuda Puran explains about life after death. It is written by social scientists to create psychological fear to govern the society. There is no heaven and hell as per Author. Each human bio machine contains bio chip, which is known as Chitra Gupt. Bio chip not only records information what it sees and listens but also it records information what ever we think. Capacity to store data of this bio chip can be increased or decreased with the help of energy in milli ampers in bio machines. After death bio chip is taken by messengers of Bio Chip Master or expert in bioinformatic, who decode this bio chip and sends back to take birth as per requirement to run this universe. This Bio Chip is near heart known as Atman Ram and it's duplicate is in mind / brain. We shall soon prove scientifically within 50 years that rebirth is possible by bioinformatic knowledge. We may develop methods to remove and engrave this bio chip from one human bio machine to the other new bio machine. Growth or scientific development can not be imagined as on today. Our sages have tried to explain this all scientific knowledge in Vedas. Garuda Puran is only explaining those developments by a story writing method.
