Those aspects of the self are what ordinarily make time into an enemy, and makes us feel driven. Time re-enters the experience of falling in love only when fear comes back, when we begin to feel that we must hold onto the love, and don't want to let go. Or we start worrying about how this new love will fit into the rest of our lives. Then time seems to exert pressure again. But in the midst of the bliss of love, the mind and its fears has no authority at all.
Sustained love has to do with struggle.
When resistance appears, intention is required. No, I think there's something in between the ego and the Self. Perhaps we could call it the noble part of the ego, that knows it has an unaccountable feeling in search of the Self. You might also call it the emerging soul. If the ego were completely insensitive, we wouldn't have a chance because the ego rules us mostly.
