andyp - the 2nd across entry doesn't have a corresponding down answer, so the following down entry is 7d (not 6d).
7d 'soul' is the def - take the starts/'tops' of the next 4 words (one of them is an extra).
But if you're referring to the next down clue - a 3 letter word for the bird (also found in a convent?) then remove 'c' from 'set on' [with one 't' removed].
