The question of right vs wrong has been answered by those we look up to for spiritual nourishment- I also encourage one to follow their ideal wherever it lead them- a cultivation of Faith and Intuition. We all have a part to play, a personality to experience-
And who exactly answered your question that day that you "look up to for spiritual nourishment"? Sometimes faith and intuition is not enough. I've been in situations where neither of those were working for me.
