You should try to hear the name He has for things

1.
You should try to hear the name
He has for things.
There is something in the phrase: “He taught Adam names.”

We name everything according
to its outward form;

He names it according
to the batin, to what is inside.

Moses waved his stick; he thought it was a staff,
Inside its name was “serpent.”

No one knows our hidden name
until our last breath goes out.

On Ilm Zahir and Ilm Batin | Manifest and Hidden Knowledge

Some of the ignorant and fools say ilm zahir (manifest knowledge) and ilm batin (hidden knowledge) contradict each other. I seek refuge in Allah. These words are shaitan’s forgeries… In reality both these knowledges are one. Ilm Zahir is like a visible lamp that transports the knower from the stage of sharia’ to the stage of tariqa. Ilm Batin likewise is a lamp that transports the seeker from the stage of tariqa to the stage of haqiqa. Both these braches of knowledge are complimentary, without which there is no progress for people.
