Sraddhatraya Vibhaga Yoga-Bhagavad Gita Chapter 17 [The Three Divisions of Material Existence]
Krishna Said > Shaloka: 12
But that sacrifice performed for some material end or benefit or preformed ostentatiously, out of pride, is of the nature of passion, O chief of the Bharatas.
Sometimes sacrifices and rituals are performed for elevation to the heavenly kingdom or for some material benefits in this world. Such sacrifices or ritualistic performances are considered to be in the mode of passion.
