THE PURPOSE OF THE RARE HUMAN BIRTH

The spirituality, Philosophy or religion all are about what is this human Life and what is the main purpose of this rare human life? No two individuals including the mono zygotic twins are similar even though they are from one sperm and egg. Why is this? How can we explain? The most probable explanation seems to be that we all are the product of five elements, namely space, air, from air fire, from fire the water, from water the Earth, from Earth, plants, from plants food, from food humans. Different from and lying within humans formed from the essence of food is the self (Atman) which is nothing but Paramathman or Brhman. Some mystical Energy (Some call it God) is identified as the source of the five elements.
Some wise men say it is inherent in Nature while others say it is Time. It is rather the greatness of Energy present in the world by means of which the wheel of Brahman goes around, who always encompasses this whole creation, the knower, the architect of time, the one without qualities and all the known ONE-it is it's command that the work of creation, to be conceived as earth, water, fire, air and space unfolds itself.
Add to the five elements, need three Gunas, from BhagavadGita (the primary qualities of Nature), Sattva, Rajas and Tamas which exist in all beings including humans in various degrees of concentration and combination. Depending upon their relative strengths and combinations, they determine nature of beings, its actions, behaviour and attitude and its attachment to the objective world in which it lives. The primary purpose of these gunas is to create bondage, through desire for sense objects leading to attachment with them and keep the beings under the perpetual control of Nature (Prakriti) from which the three gunas arose. And this the reason no two individuals are similar.

The purpose of human life is Liberation from this Samsara (birth, old age and death) utilising our unique gift of intellect (Buddhi) which can discriminate what is temporary and permanent, what is good and bad. Liberation is also called by different names such as, Mukthi, Moksha etc.
According to the law of Karma, we need to born again and again to bear the fruits of our actions whether good or bad, so how can we get Moksha?
There is a simple and easy way in our Sanathana Dharma which is whatever we do, we need to dedicate to the Lord of our choice 100% by which the fruits our action will not effect us but to the Lord himself or herself hence there is no need for rebirth and no death and we (Athma) can go from where we came to Brahman forever which is our mission of human life.
Hope it is clear and easy to practice which is in our own control.
This is the essence of spirituality/philosophy of life.
