Belief in Hindu gods or deities
the caste system
Step-by-step explanation:
for the caste system: Buddhism suggested that individual people might be able to attain enlightenment in this life and held that caste was not a punishment for deeds committed in a past life; which also allowed women to become Buddhist monks and to work outside the traitional sphere of family and home (Khan academy . org)
Buddhism was part of the Monoastricim (religious way of life) that involves leaving behind worldly pursuits and devoting oneself to spirital activity; teaching through the Four Nobel Truths (guiding principles).
