Sant Kirpal singh (the disciple of Baba Sawan Singh)has spread this movement in various parts of the world.He has written various books which contains the teachings of various religious scripture including Guru Granth Saheb,Quran,New Testament,Vedas and various mystics including The Sikh Gurus,Kabir,Hafiz,Mailana Rum,Khwaja Gharib Nawaz,Mira,Dadu etc.
In his books he has constant mention of sayings of Hazrat Shah Niyaz R.A.
Starting with his book "Gurumat Sidhdhant" which he wrote on instruction of His Guru Baba Sawan Singh and published it in his name,while discussing about the true lover of God who has no attachments towards the world he quotes Hazrat Shah Niyaz-
I have sacrificed the austerities of this world, my meditation, etc., at the Lotus Feet of my God. My religion is love for Him and to be intoxicated in that bliss. I keep myself dyed in the colors of His Love. Oh, you ascetic! Please listen to me in the name of my God! You should discontinue your austerities and rituals, and instead should drink the cup of wine of the Love of God. The intoxication from that bliss is much more exhilarating than any other intoxication. You cannot find such bliss anywhere else.
After that Sant Kirpal says that Lovers do not believe in salvation by means of reading scriptures alone. They read only the scripture of love and quotes Hazrat shah Niya R.A.-
O my Lord! Teach us the one word of your love. I do not wish to waste my life in reading stories about you.
In the same book while discussing shabd(audible God) he compare it with Sultan-ul-Azkar the sufi practice of repetition of Ism-e-Azam(the greatest name).He imphasizes on the sufi belief of the inner voice being the voice of God,which is called as Kalaam-e-Elahi or Sot-e-Sarmadi.Here he again quotes Hazrat Shah Niyaz R.A. who said -
The world is filled with the Divine Sound, open the portals of your ears; listen to the Eternal Sound; It is beyond the reach of dissolution
Continuing the same Sant Kirpal says that the beloved is always speaking to us but we do not listen to him and quotes Hazrat Shah Niyaz R.A. who said-
My Beloved is always addressing you. Alas! You listen not to the words of the Ancient One.
In his another book named Naam or word,which also deals with the consepts of Naam,Shabd and Kirtan Sant Kirpal mentions Hazrat Shah Niyaz R.A. in various places.He gives evidence of concept of Naam in various religion and coming to Islam he quotes with others Hazrat Shah Niyaz R.A. who said-
Soul is the Will and the Secret of God. Its meditation is carried on without the help of tongue and palate.Alas! Thou art stuck fast in the physical bondage and do not hear the Holy Sound of God. My Beloved is speaking to thee all the while, but woe to thee for thou heareth not the Voice.
Again Shah Niyaz R.A. says-
The whole universe is resounding with the Sound, and thou hast only to open the door of thine ears.For opening the ears, it is sufficient to stop hearing the outer sounds. If you do this, you will hear the perpetual and unending Sound. It is infinite and has no beginning nor end, and on account of that,It is called Anhad (i.e., without any limits). Without this Word-the Eternal Sound-an expression of the Infinite, the world could not have come into existence. Hold communion with the Melodious Sound and lose yourself in it, O wise man.
Referring to the Sound in teachings of Sufis he quotes Hazrat Shah Niyaz R.A.-
The whole world is reverberating with Sound,To listen to It thou must unseal thine inner ears,Then shalt thou hear an Unending Music,And that shall lead thee beyond the confines of death.
In the same book Sant Kirpal tells that we can tune with the divine sound if we can introvert and stop listening to the outer sounds of the world around us and quotes following saying of Hazrat Shah Niyaz R.A.-
Sound is pervading the whole world in Its fullness,
Ye can surely listen to It with transcendental hearing,
This ye can do by closing the outer bodily ears,
For surely then shall ye hear the endless song,
And It shall take you beyond the sway of destruction and dissolution.
Discussing on Anhad Naad,the devine sound which doesn't depend on any limitations,he describe Anhad as unceasing, eternal or limitless sound as the term literally means and quotes the saying of Hazrat Shah Niyaz R.A.-
Hear thou one continuous and unending Music,
A music that is eternal and beyond the confines of death.
When It has no beginning and no end,
It is therefore called Anhad or endless.
In his book "Jap Ji" which is the a translation of Bani of Guru Nanak he quotes the above mentioned saying of Hazrat Shah Niyaz R.A. related to Sultaan-ul-Azkaar and Ism-e-Aazam.
In another book named "Crown of Life" Sant Kirpal while telling that God has given us the outer ear to enjoy the melodies of sound, and the inner hearing with which we may hear the Voice of our Creator he quotes Hazrat Shah Niyaz who wrote-
Oh God, lead me to the place from where flows the ineffable
Kalma without words
