The reviver of Islam Shaikh Ahmad Sirhindi (Allah have mercy on him) wrote to one of his deputies (khalifa),
‘Be concerned about your own affairs (that is, your relationship with Allah), so that you leaves this world safely (with eman).
In the hereafter certificate of authorization (ijazet-nama) or (increased number of) disciples will be of no help.
Indeed! While managing your own affairs if anyone comes (asking for guidance explicitly) with sincere yearning then instruct him about the path. However, do not make the instruction about the path (tariqat) your main goal and management of your own affairs subservient to this. Doing so will be an affliction and loss for you.’
