Bhagavad Gita 4.32

एवं बहुविधि यज्ञ विटता ब्राह्मणो मुखे |
कर्मजान्विद्धि तान्स्रवानेवं ज्ञात्वा विमोक्ष्यसे

Translation

All these different kinds of sacrifice have been described in the Vedas. Know them as originating from different types of work; this understanding cuts the knots of material bondage.
