What is the purpose of Life? What makes the human life different from the other creatures? The answer is Purushartha. To give to the world is more important then what you takes. Giving you human life, that can think and evolve itself is the biggest gift by the nature. So what we give back to the nature? One must have a goal in life, that can help human-kind, animal-kind, environment, or any forms of nature-kind in harmonious sync with nature’s eternal laws. Realizing the significance of human birth through benevolent actions is Purusharth. Purush is one of the two key components of Brahm, which comprise entire metaphysical world. Souls are an infinitesimal part of Parampurush, yet ignorant to this fact, it commits numerous mistakes. This is why every individual has two-some inside, one is the desire driven soul and other the element of God, the Parampurush. When Purusha’s element in people is recognized by souls, it is ‘yog’. In 'yog, bodied listen to Gods within. Materialism linked to bodies dissolves in this knowledge. This is when people tend to derive the purpose in life and engage in deeds that signify the worth of their souls. This is Purusharth, i.e. significance and purpose of the soul, not bodies.
By incessant practice of Yog, controlling the conscious mind from meandering or wavering, thus, contemplating and meditating on him, the resplendent Parampurush is attained, O’ Arjun!
Purusha, (the individual soul) while situated in Nature, experiences and acts due to nature-born qualities and due to such associations with Triguna qualities, determines their future births (as good or evil spirit).
One’s innate nature is constantly being upgraded or downgraded by the cumulative effects of one’s deeds. Rise to beatitude is a constant struggle through deeds with higher consciousness. Thinking mind with true egalitarian spirituality and intellect, irrespective of whichever religion he or she comes from, can see alignment of thoughts and actions, due to conceptual understanding, not those remaining at surface for glib practices alone. On the other hand, low consciousness narrows one’s thinking down and disorient people. A fundamentalist reborn in another religion will be equally fundamentalist but for the other religion. It is an oxymoron that fundamentalists, indeed, do not know the fundamentals of the religion. Enlightened, one seizes to be fanatics, and realizes the role in life and enact Purusharth. Thus, they succeed in achieving salvation.
