I was actually thinking of a slightly prolonged visit. I dont know what he does professionally but maybe he could come here and see if there are startups / companies / univs doing interesting things in his field. I was thinking along the lines of -he comes here, meets some people who are doing interesting stuff in his field, finds a footing and passion for the field and gets some direction - perhaps enrolls in a post grad univ. Sometimes the reason people turn to philosophy books is because they arent finding the intellectual challenge that they crave in their daily life. In India careers can often seem mundane and maybe putting him in contact with people who are close to how he wants to be would solve his anguish and make him feel that good things are possible.
