I take as a starting point the last sentence of the Editorial in Vol. I of the new Bulletin: "With a few notable exceptions...contemporary Hindu thinkers do not seem to be engaged with Christianity in the way their predecessors were at the turn of the century (e.g. Roy, Sen, Dayananda and Radhakrishnan)". This is a very insightful observation and it is worth dwelling on. Let us begin from the "Christian side" first. What considerations are encouraging some Christians to "take an interest" in Hinduism. Listing some of these may be convenient although probably too schematic, for combinations of the following are often to be found.
