Devapuja or Worship of God this bookby Swami Harshananda serves as a comprehensive guide to the philosophy and practice of divine worship within Hindu tradition.

The book  explains that ritualistic worship (puja) acts as a stepping stone or "kindergarten of religion," helping restless minds achieve inner purity, focus, and spiritual discipline. Differentiates between external worship (ritualistic practices using symbols, images, and consecrated articles) and internal worship (manasapuja or deep mental contemplation/meditation).Emphasizes that external rituals are meant to cultivate inner devotion and introversion, ultimately leading the seeker toward formless meditation and spiritual realization where formal rites naturally fall away.
