Srimad Bhagavad-Gita :
Chapter-5. ( Karma-sanyasa-yogam )
However, We must give credit to the strong, deep, tattvam of Gita.
A flower should change into unripe fruit, that is the flowers' desire / fate / saphalyam.
In this prikrya ( activity ) there is destruction to its previous state, i.e, flower fades and drops.
We see an unripe fruit in place of flower now.
Because of this no one laments about the destruction and loss of flower.
Flower discarded its unnecessary parts, and its essence in the form of unripe fruit.
That is all.
Considering the above we can say that if Vedik literature is flower, then Gita sastram is its fruit
The activities or rituals put forth in the karma-kandam of Veda-s, the unnecessary rituals are discarded, and the essence of Veda-s, that is a complete jivitha-sastrm ( life-science ) took shape in a text namely, Srimad Bhagavad-Gita.
