Surely love must also be one of those portals?
No, it isn't. As soon as one of the portals is open, love is present in you as the "feeling-realization" of oneness. Love isn't a portal; ifs what comes through the portal into this world. As long as you are completely trapped in your form identity, there can be no love. Your task is not to search for love but to find a portal through which love can enter.
