Shaikh Umar Birbalwi (Allah have mercy on him) said,

‘The perfect spiritual mentor (pir-e-kamil) is one who does not let the disciple to burnout ( tire or give up on this path due to his short comings).

Similarly, an adept disciple (kamil murid) never tires out (and gives away hope of achieving success. He is persistent in his effort to please Allah.)’
