Mahatma Gandhi set the example at his fag-end of life and his daily prayer meetings in the midst of gravest political occupation must be taken note of. So also in the Bhagavad-gita. The Arjuna in the gravest moment of warfare learnt the teachings of Bhagavad-gita & he changed his personal opinion in the manner of the fighting.
So the present process of human thinking for material gains only has to be changed by an organized preaching work of Bhagavad-gita as done by Lord Caitanya not only for the benefit the people of India but also for all people in the world. Lord Caitanya's way of preaching is ___ but a practical demonstration of the way of Bhagavad-gita. No amount of dry speculation by easy chair empiric philosophers will be able to implement the teachings of Bhagavad-gita unless we adopt the practical ways of Lord Caitanya as above mentioned.
