The Roots of Abstractness...

Firstly as Baba Bulleh Shah (my guide) has suggested...
ਉਹਨੂੰ ਲੱਭਣਾ ਤੇ ਖ਼ੁਦ ਖੋ ਜਾ ਤੂੰ...
(If you want to find Him, be lost yourself !)
So after getting immersed in the sea of purity...The human soul becomes ready to understand HAQ i.e. The Eternal Truth...
In this situation, the bliss begins and I would like to say on behalf of the lost soul :

ਅਸੀਂ ਛੱਡ ਕੇ ਸ਼ਾਹੀ ਦੁਨੀਆ ਦੀ, ਉਹਦੇ ਨਾਂ ਦੀ ਫਕੀਰੀ ਪਾਈ ਹੋਈ ਏ...
(I have left the worldly royalities and have worn the cloak of His faqeeri on my soul !)

And the next vital pre-requisite to understand this abstract beauty is emptyness within !
As the sufi saints say :
ਮੇਰੇ ਵਿਚ ਮੇਰਾ ਕੁਝ ਵੀ ਨਹੀਂ...
(I have nothing in me that I can call mine !)
