God says that He is nearer to man than his jugular vein,
then how can we make a journey towards God?
Abū Ḥāmid al-Ġazālī r.h (1058-1111), a Mujadad of his time,
explains this phenomenon as follows:

 وَ نَحۡنُ اَقۡرَبُ اِلَیۡہِ مِنۡ حَبۡلِ الۡوَرِیۡدِ

And We are nearer to him than even his jugular vein.
(The Holy Qur’an 50:17)

ہر حال میں بس پیشِ نظر ہے وہی صُورت 

“One in one, One in Many, Many in One, Many in Many.”

Hwa Yen school of Buddhist thought talks about a similar concept in the following story: 

The Empress Wu, who had difficulties understanding the complexity of Hwa Yen philosophy, asked Fa Tsang, of the of the founders of the school, to give her a simple practical demonstration of cosmic inter-relatedness. Fa Tsang took her to a large hall, the entire interior of which – the walls, ceiling, and floor – was covered with mirrors. He first lit a candle in the center of this hall and suspended it from the ceiling. In the next moment, they were surrounded by myriads of glowing candles of different sizes reaching the infinity. This was Fa Tsang’s way of illustrating the relationship of the One to the many. 

He then placed in the center of the hall a small crystal with many facets. Everything around the crystal, including all the countless images of the candles, was now collected and reflected in the small interior of the brilliant stone. In this way, Fa Tsang was able to demonstrate how in Ultimate Reality the infinity small contains the infinitely large and the infinitely large the infinitely small, without obstruction. Having done this, he pointed out that this static model was actually very limited and imperfect. It was unable to capture the perpetual, multidimensional motion in the universe and unimpeded mutual interpenetration of Time and Eternity, as well as past, present, and future.
