[Avodah] Intuition - sources

[Daniel Eidensohn]

I am interested in sources which say to rely on intution to know answers 
for spiritual and existential issues.

Have the following so far:
The Seridei Aish says that faith is intuitive rather than rational
Chovas HaLevavos (4:3) says that one knows which is the correct job 
because it is enjoyable.
Avoda Zara (19a) One should learn that which the heart desires
Gra in Mishlei says theortically we know intitutively what our avodas 
Hashem is but since we are not spiritual refined enough we can't rely on it.

Any source that  "G-d wants the heart" that one should do that which  
seems intutively correct?
