Walk in search of Knowledge and knowledgeable scholars
until no further walking is possible. Walk until nothing obeys you
[in your wish to walk]. When you become unable to walk,
sit down. Walk with your outward, then with your inward,
then with your heart, and then with your essence.
When you have become totally exhausted outwardly and inwardly
and have to sit, nearness to Allah (mighty and glorified is He)
and attainment to Him will come to you.
Sheikh Abdul Qadir Jilani
