Acharya Prashant explains that the reason Dhritarashtra could not benefit from the Shrimad Bhagavad Gita despite hearing it is that he was unwilling to pay the necessary price. He contrasts this with Arjuna, who was prepared to sacrifice his kith and kin. The speaker emphasizes that spiritual knowledge is like a merchandise demonstration; one cannot take it home without being ready to pay the cost. In the case of the Gita, the price was the immense struggle of the war. He asserts that in the supermarket of life, what an individual receives depends entirely on what they are willing to pay, rather than what they merely like or desire.
