The poem describes Buddhist monks as soldiers marching to spread Buddha's teachings. It discusses hearing their footsteps and seeing their banners as they march through important Buddhist sites like Lumbini, Bodhgaya, and Sarnath. However, rather than fighting for an earthly king, they battle illusion and darkness with righteousness, wisdom, and the Buddha's teachings in order to help mankind progress. The soldiers aim to spread Buddha's message of truth and love throughout the world.
