Here is an excerpt from Bhaktivinoda Thakur’s book Krishna Samhita:
Those who are endowed with spiritual vision can recognise foreign saragrahis as fellow yogis. Komola-Sraddhas (Those of simple faith) and those who are inexperienced think if them as worldly or sometimes even against God. But saragrahis can easily recognize their fellow spiritualists, who are endowed with all good qualities, whether of their own country or foreign. Even though their customs, symbols, worship, language, and dress are different, they easily address one another as “brother”.
Apart from adding sister to the last word, I find tremendous inspiration from these words. The truth is one, the wise sages will call it by many names. There is the ultimate end of all interfaith dialogue.
