Some modern Hindu scholars use the "Vedic religion" synonymously with "Hinduism." According to Sundararajan, Hinduism is also known as the Vedic religion.

Vedas inspired later Hindu scholars such as Adi Shankara to classify each Veda into "karma-kanda" (कर्म खण्ड, action/ritual-related sections) and "jnana-kanda" (ज्ञान खण्ड, knowledge/spirituality-related sections).
