After a Spiritual Journey: Bread and Wine

I heard a wonderful teaching today from my teacher Avraham: according to Jewish tradition, when a person returns from a mercavah journey, having visited the heavenly palaces, and stood in the presence of God, the best thing to do is to eat and drink.

To me, this is pure technique: when someone has been meditating deeply or journeying, one of the best ways to ground oneself and bring oneself fully back to the physical world is to eat.

In Genesis 15:18, during the meeting of Avraham Avinu and King Melchizedek of Salem, we are told that "Malchizedek of Salem brought out bread and wine". He then gives Avraham avinu a blessing.

Another story Avraham my teacher relayed was of a Hasidic rabbi who was known to rise up to the heavenly realm during prayer. He had a hasid (disciple) who's job it was to hand the Rabbi bread and butter when he finished praying so that he could return fully to this world.

I believe there is another textual source, but haven't been able to find it yet. I'll post when I do.
