Man does not Live by bread alone but by the Will and Word of the Divine.
After being baptized by the Holy Spirit (in far east traditions Kundalini, Supramental Grace Light, Chi) Jesus was directed to fast and meditate in the desert for 40 days and 40 nights in order to know Hunger (The Devil).
Satan (Hunger) mocked Jesus and urged him to prove his Divinity by turning rocks into bread. In reply He quoted the Old Testament, citing the case of the Israelites wandering in the desert for 40 years, humbled and purified by Hunger "so that they might learn that man does not live by bread alone but by every Word that proceeds from the mouth of God".
What is Hunger? We commonly know it as a craving, desire or need for digestible food substances. We give Thanks once in a while for the temporary and partial satisfaction that we experience upon eating. But Hunger for food and Hunger for possessions, power, status, recognition, love or any perceived lack are all the exact same Hunger. The illusion that we are satisfied and fulfilled only by the acquisition and consumption of externalities is Hunger.
The Truth, hidden and obscured by Hunger, is that ONLY the Grace Light of the Divine fulfills. And this truth encompasses not only the less tangible emotionally based wants, but the physical cravings for digestible food substances as well.
We are NOT sustained exclusively nor even primarily by the ingestion of food but by the Will of the Divine. FOOD IS A SUPPLEMENT to the Word of God. Where our capacity to accept and channel Divine Will through our bodies is lacking, food satisfies the deficit.
We are now coming to Know that our power and sustenance can be entirely received from Divine Source directly in a Life that is lived in full Surrender and alignment to Divine Will.
