I agree that there are some similarities in all the religions. Serving poor people is a divine work. This was done perfectly by Ambedkar. So he is better than yogis. Jesus resurrected from death. And Jesus sacrificed his worldly life for people. That make him different from what you call yogis. What we call prayer is not much different from what you call yoga. We used to close our eyes and pray God without any idols. Without concentration one cannot do this. By praying God telling all your sorrows and agony to God in a silent place you are having a spritual relationship with God. Wherever you go you will have a feeling that a Power is with you to guide you.
