This classic spiritual work is an interpretation of the Bhagavad Gita focused on Karma-yoga (the science of selfless action) rather than mere renunciation. Written by Lokmanya Bal Gangadhar Tilak during his imprisonment at Mandalay, it presents deep philosophical insights into duty, action, and life’s purpose. The text emphasizes Nishkama Karma—performing one’s duty without attachment to results—as the core teaching of the Gita. It includes commentary, translation of key verses, and analysis that bridges traditional wisdom with practical life lessons. Regarded as both a religious and philosophical classic, it remains influential for students of Indian thought and spiritual seekers alike.
