"[3] Another interpretation of its origin is that it is derived from masti, a Persian word meaning "overpowered.
"[4] According to Meher Baba, a mast is one who is entranced or spellbound by internal spiritual experiences and ecstasies, who cannot function outwardly in an ordinary way, and may appear mad to a casual outside observer.
In The Wayfarers: Meher Baba With the God-Intoxicated, British medical doctor William Donkin documents at length Meher Baba's contacts with masts throughout South Asia (primarily Iran, India, and Pakistan).
The introduction, written by Meher Baba, explains their unique state and their outward characteristics.
Meher Baba contacted thousands of masts all over India, Pakistan, and Iran, saying that he was freeing them from enchantment and helping them to continue on the spiritual path and to be of inward service to humanity.
