Shaikh Zarruq (Allah have mercy on him) said,

‘Tasawwuf has been defined and explained in multiple ways. They number approximately two thousand.

(However) All of them refer to a single objective.
(That is,)
True, sincere and absolute attention towards Allah.

This is the objective in all the paths (turuq).
And Allah knows best.’
