For some information on the 13th c. Indian Sufi Sharafuddin Maneri, see this post.

O heart, if you go seeking along His way,
Look carefully in front and behind, and only then proceed!
Look at the travellers who have arrived at His threshold,
Generation after generation have arrived together!
How do you know about which road to take?
How can you know which one leads to His threshold?
For every single particle there is a particular entrance:
Yes, for each particle there is indeed a separate road to Him!
