Deva = bright beings = islam says angels are made from light. So devas are angels and sanatan dharma is their teachings.
Bible says (angels are servants of righteousness)
From this info we could assume DEVAS- bright beings are what islam and christians call angels, and sanatan dharma is their teaching of righteousness.
2 Corinthians 11:14-15New International Version (NIV)
14 And no wonder, for Satan himself masquerades as an angel of light. 15 It is not surprising, then, if his servants also masquerade as servants of righteousness. Their end will be what their actions deserve.
