Thanks for your response. It was mentioned on the Harvard website that if you do not have an undergrad degree in humanities, you should take some courses related to the program you want to apply for. There are some courses offered on Edx by Harvard university related to religion, do you think taking these courses will improve my chances? Also, as I don't have any related experience, how shall I structure my SOP. Shall I only talk about my interest in comparative religion? Plus, shall I take my Letters of Recommendations from teachers who taught me Humanities related subjects in Engineering or can I ask my manager at work too? And can you please guide me on important points that I should cover in my SOP and LORs. Also, does Harvard or other good universities offer any scholarship for these programs? As I am from Pakistan, I would need assistance not only for paying tuition fee but also for living and other expenses. There is a Full Bright program in my country to which I can apply but I think it will be harder for me to be considered for that in my situation..
