Sheikh-o-brahman
The Muslim divine and the Hindu priest; the two orthodoxies the free spirit transcends.
Literally: the Muslim cleric and the Hindu priest
Sheikh-o-brahman pairs the mosque's cleric with the temple's priest as the twin faces of religion-as-formalism — both correct, both quarrelling, both missing the love that the rind has drunk in the tavern. The phrase lets the poet stand above sectarian dispute and side with love over law. Iqbal uses it repeatedly to argue that the wine of divine love dissolves the very boundary the sheikh and the brahman keep fighting over.
Shaikh
An elder or religious authority; in ghazal often the sanctimonious figure set against the rind.
Barhaman
A Brahmin or Hindu priest; in Persianate poetry the idol-temple's keeper, a counterpart to the Muslim cleric.
Dair
A temple or monastery, especially of the Magians or idolaters; the tavern-shrine of the free lover.
Zaahid
An ascetic, an austere pietist; in ghazal the killjoy foil to the wine-loving rind.
