On the spelling of Krishn.....i believe that if you actually read the ISCKON pronounciation guide of the word KRSNA, both Krishn and Krsna should have the same pronounciation...the problem being that there is no perfect manner to write Krishn(a)'s name in English.

There are numerous similarities between Jagadguru Kripalu Maharajji and Lord Caitanya. i am currently reading Caitanya Bhagavat and everyday my breath gets taken away when i read some leela of Mahaprabhu or His virtues which are identical with Maharajji. Like someone else here said, it is up to you to decide on what He is for you
