Jyon Naino Mein Putli, Tyon Maalik Ghat Mahin
Moorakh Log Na Janhin, Baahar Dhudhan Jahin
Like the pupil in the eyes
The Lord resides inside
Ignorant do not know this fact
They search Him outside
In this Doha, Kabir using a very apt simile demonstrates the fact that God is within everyone. The wise thus realize Him by introspection, while the ignorant search Him externally.
God is unseen and inexpressible. Anything that is seen, can be counted or measured, automatically becomes mutable. But God is not mutable.
We can see a bunch of flowers, count them, weigh them, but how can we see, count or weigh the fragrance? Same way, the Atman of the Hindu, the soul of the Christians is that representation of God that resides within everyone and is yet unseen, unknown, incomprehensible and inexpressible.
