If I want to summarize Indian philosophy ( includes Vedanta, Upanishad, Buddhism, Jainism, Sankhya, Nyaya, Mimansa, Charvaka, Advaita school of thought) then one line can describe its essence.
“Truth can be stated in a thousand different ways, yet each one can be true.”
You call it God, Allah or Ishwar (Indian word for God though we have many names) it’s all same.
Our starting point can be different or ways can be different but end is same.
And best way to practice good is to doing ones duty with happiness. Doing ones duty to achieve excellence and creativity.
As Buddha said rightly, “Do good and be good.”
