Shiva keeps Trishul, Damru, Kamandal, Khappar and Jholi along with him all the time. Shiva wears a "Mala of Snake" and "Bagamber (Skin of a tiger)" as his sitting place (Asana). Shiva's consort is Shakti - The Mahadevi. Shiva says a true yogi carries all this along with him.
It is everywhere mentioned that Lord Shankar is an incarnation of Gorakshnath. It 's in Gorakh Puran, Gorakh Chalisa and every literature related to Gorakshnath.
So the "Alakh Purush" is a supreme form of a God. He is Gorakshnath. People call him Sada-Shiva and Param Vishnu. No one as on date have seen Sada-Shiva and Param Vishnu because these are formless, shapeless ("Nirakar") forms of Gorakshnath.
As the Mantra of Chimta suggest, it is the Gorakshnath Chimta which made the universe alive (Make each one of us awake) after Brahma, Vishnu and Shankara just created. Now the reader of this post must be thinking how this can be possible with Chimta. What Brahma, Vishnu and Shankara created were just bodies without a soul. This science of putting a soul in a body is with Gorakshnath (Alakh Purush). First Gorakshnath put the soul in each one of us through his "Nad Janyu" and then using a "Chimta", he made all of us awake.
The dead body is popularly known as "Shava" in Hindi. When "Shakti" combines with "Shava", it makes "Shiva". Shiva means anything which is alive ("Chetan"). It is "Nad Janyu" that Gorakshnath wears, generates "Shakti" which combines with "Shava" and that's how Shiva gets generated. This also proves "Shakti", the Universal Mother was there before Brahma, Vishnu and Shankara. Gorakshnath generated the "Shakti" first and then it is distributed everywhere to make the universe alive ("Chetan").
"Nad Janyu" and "Chimta" are two things in which Gorakshnath differs from Shiva as I described above.
"Sab Guru Gorakshnath Ji Ki Maya Hai, Chimta Se Sabko Jagaya Hai ! Isiliye Shankar Mahadev Ne Alakh Niranjan Gaya Hai !!"
I (Bhuwan Joshi), bow down to the feet of my Guru Gorakshnath Ji!
