Rambam - Hilchot Beit Habechirah 7:15 The Laws of God's Chosen House THE TEMPLE MOUNT - Next Level Sanctity. Live Impure & the Dead. Moving in from Jerusalem, we enter the sacred Tabletop Mountain Plataea that housed the Beit HaMikdash arena. A higher level of Ritual Purity restrictions and observances reflects the Greater Holiness, as we are now moving onto Next Level Sanctity. Surprisingly, the detailed list of individuals proscribed from entering do not include the most extreme form of Tuma'ah as in this inner scrimmage of holiness we are permitted to Welcome the Grateful Dead, and the Undertaker too!
