Acharya Prashant explains that in the current era, it is no longer possible to realize the truth and remain passive or withdrawn from society. He contrasts the peaceful, contemplative atmosphere of the Upanishadic era with the battlefield of the Bhagavad Gita. While ancient disciples might have retired to forests or simple chores after gaining knowledge, Shri Krishna’s teachings compelled Shri Arjun to immediate action in war. He asserts that today’s world is a modern Kurukshetra, where spiritual knowledge must be translated into action; failing to act after gaining insight is described as an insult to Shri Krishna. He further illustrates this shift through the Sikh tradition, moving from the peaceful message of Guru Nanak Dev to the call for the sword by Guru Gobind Singh. He explains that while the spiritual essence remains constant, the 'duty of the era' or Yug Dharma changes according to the environment. Today’s spiritual seeker cannot remain a hidden devotee or stay confined to a room; spirituality must be active and socially relevant. He critiques the traditional concept of a monastery, suggesting it must now function as a fortress for conducting a struggle against modern evils like greed, environmental destruction, and the exploitation of nature. Acharya Prashant identifies the modern enemy as being far more cunning than those of the past, often hidden within systems of consumerism and even within one's own mind as lust and selfishness. He emphasizes that one should not wait for total internal perfection or the complete removal of fear before taking a stand. Even Shri Arjun trembled and faced weaknesses throughout the war, yet he continued to fight. The speaker concludes that the most inspiring battles are those fought despite one's limitations and fears, and that the act of fighting for the right cause is itself the victory.
