Upasana
Upasana (Sanskrit: उपासना upāsanā) literally means "worship" and "sitting near, attend to". It refers to the worship of, or meditation on, formless things, such as Absolute Self, the Holy, the Atman (Soul) Principle, distinguishing meditative reverence for an internalized and intellectual concept from earlier forms of physical worship, actual sacrifices and offerings to Vedic deities.
