That higher "you," deep inside, that "you" that guides you, loves you, is your Spirit. It's actually a small piece of the Universal Spirit, a tiny piece of God inside you. I'm not talking about the part of you that thinks and that conducts your inner dialogue. It's the you that witnesses that. It's the silent observer, the central point above all. Your "higher self." It's an omnipresence that is you, and at the same time is bigger than you.
Some Christians call this the "Christ" Spirit, or Holy Spirit. Some Jews calls this Ruach (or breath of life/wind). Some Hindus speak of Atman, or seat of consciousness. Buddha described this presence sometimes as "self/no self." I believe this part of us is so beautiful it is almost indescribable. Words and concepts fall far, far short.
Whatever your beliefs or traditions, you can find this Presence inside you, and it will guide you. You can go to this point, this Love, anytime, and you will no longer need your petty, useless bad habits as comfort.
