Identify the Hindu beliefs. Only a priest can speak directly to God. The world is not real. It is an illusion that simply feels
emmainna [20.7K]

Answer:

The world is an illusion is the only possible answer.

Explanation:

Hindu priests do not claim to be able to spek to god, and since they are polythiestic they do not believe in one god. They do believe in a specific set of gods however so they would not believe that god is formless. They also believe in Karma and reinecarnation so ``We only live once`` would not be a viable answer either. To my knowlage ``The world is an illusion`` is not a core hindu belief either so I would question your teacher about that.
