The Human body which is like any other machine is being used by the spirit for performing various acts to contemplate with the objects of the material senses but a question arises whether the embodied spirit within wants to respond to the objects of the material world or is it forced into this situation and forced to act accordingly or as the Gita says that spirit within performs no actions but due to contact with the three modes of material nature thinks itself to be the doer which actually are performed by the three material modes and the spirit (self) within does nothing at all?, hence in any situation as one has to act, perform your actions but with no fruitive desires of gain or loss, victory or defeat, thus putting efforts to transcend the three modes of nature and also remaining satisfied with gain that comes of its own accord.
In Bhagwad Gita chapter 14 its mentioned when the embodied being is able to transcend these three modes associated with the material body he can free himself from birth, death, old age and their distresses and can enjoy nectar even in this life. This sounds really amazing. A person who thus remains neutral, away from all kinds of dualities and clearly is aware all the time that the three modes of material nature are active alone and he being situated in self and one who has mentally renounced all material activities, one who does not hate illumination, attachment and delusion when they are present or long for them when they disappear, who is unwavering and undisturbed through all material reactions, who looks upon a lump of earth, a stone and a piece of gold with an equal eye, who is equal and same towards desirable and undesirable, praise and blame, honor and dishonor, who treates a like a friend and enemy, such a person is said to have transcended the three modes of nature.
Looks difficult to materialize the above system but still the though comes that it is so true that all material activities and its results are temperory hence what need is there for all this anxiety and dualities which only causes one thing and that is bondage.
The continous cycle of birth, youth, old age and death cannot be the final reality. There has to be something more meaningful beyond this. That feeling of Self - "I am Bharat Bajaj or I like so and so things and I dislike so and so, that feeling of "I" never changes even as one passes from childhood to youth to old age. The age of that "I" never grows and it never took a start, it already existed before, its same at present and will remain same in future.
It seems that that "I" is the real truth and everything else is false and non permenant and that "I" doesnot have a human nature, its existing but without any nature and without any dualities
