Puja

Central to Worship: Yajnas, meaning sacrifice or offering, were the central mode of worship in Vedic times. These elaborate rituals involved chanting hymns, offering oblations (ghee, grains, milk etc.) into a consecrated fire, and performing specific actions guided by priests. 

These ancient epics like the Vishnu Purana, Shiva Purana, and Devi Bhagavata Purana describe the significance of Puja as a way to connect with and worship various deities. They often narrate mythological stories that illustrate the power and benefits of performing Puja correctly.

This central text of Hinduism mentions Puja in the context of selfless service and devotion to God. It emphasizes the importance of offering one's actions and thoughts as a form of Puja, rather than focusing on material offerings.

These are a collection of Tantric texts that provide elaborate rituals and instructions for performing Puja. The Pancharatra Agama and Shaiva Agamas are particularly focused on Puja rituals, outlining the steps, offerings, mantras, and symbolic meanings involved.
