Talking about the Light form of that one Supreme and Highest Truth, such as Naam, Satnam, Waheguru or Akal Purukh;
found the following 2 utmost beautiful and truly universal messages in the Bani for all mankind, and any living/consciouss beings :
ਨਾਨਕ ਠਾਕੁਰੁ ਸਰਬ ਸਮਾਣਾ ਆਪਨ ਭਾਵਨ ਕਰੀਆ
Naanak Thaakur Sarab Samaanaa Aapan Bhaavan Kareeaa
O Nanak, the Lord and Master is contained amongst all; He does just as He pleases.
and
ਪੂਰਿ ਰਹਿਆ ਘਟਿ ਘਟਿ ਅਬਿਨਾਸੀ ਥਾਨ ਥਨੰਤਰਿ ਸਾਈ ॥
Poor Rehiaa Ghatt Ghatt Abinaasee Thhaan Thhananthar Saaee ||
The Imperishable Lord is permeating and pervading each and every heart; He is in all places and interspaces.
*We can see, how Guru Jee tells us that, that formless and eternal Lightful Truth, is contained in all, and there is no such place where He is not.
He is not limited nor is a copyright to any particular tribe, geographical zone, country, race, or nationality, He is present even in those who acknowledge Him not and deny Him, yet He is present in all, thus, our consciouss state as souls.
Bodies are fanah, perishable. It is by the one ray of His Light, His akhoot Jot, present in that body, which makes us consciouss and sentient living beings, throughout the Chaurasee ka chakar.
The teachings of Guru Sahiban and Bhagat Jan, are universal, for they see the Jot of One Waheguru in all, though howsoever deluded and ignorant many could be, and as said before, the validity and truth imparted by Guru Sahiban may be rejected or not acepted by many, yet is the only universal Truth.
it is only, that due to their individual or collective destinies, due to their own karam, their time has not come yet to know and understand Him.
But, that does not change their inner reality, which is, that each and every soul, is His ray, His jeev atma.
Stay blessed.
