IMHO...jealousy is a dirty habit we pick up along the way in devolping our sense of self and ego stemming from competition. Jelaousy comes from ego. With Spirit, one things ins't better than the other, they just are. No need to be jealous because one respects the other's journey as being a fellow traveler. We are meant to cooperate, not compete.

If some one feels jealous, I suggest stepping their game up and start bringing goals to the table that make them feel good and to nourish Self, not with the goal to look good to other's. Take that energy and apply it in personal growth, not depreciation of your Self.
