The essence of all religions is one. Surrender is the main duty of everyone. Surrender means the feeling of oneness, I and God are One. The reason is, who that is present in you is present in me. Only bodies are different.
Bulbs are different in wattage and colors.
But the current is one. This book contains that important dictum of oneness that runs through all religions. One manifests in many. Only one God is present in every one. Never follow the differences basing on the differences of the body.
