Baptism in the Divine Fire
The next stage of cognition of the depth of the multidimensional Absolute implies cognition of the subtlest Divine Fiery Manifestation.
Thus God-the-Father manifests Himself to His worthy disciples who attained proper refinement of the consciousness ï¿½ in a gigantic anthropomorphic (resembling human body) Flaming form, which does not burn them.
In this Fiery Form, Ishvara is also described in the Bhagavad Gita  by Arjuna who saw Him like that: ï¿½I behold Youï¿½ like a blazing flame or a dazzling Sun, You radiate the rays of light hard to look at!ï¿½ (chapter 11:17) and ï¿½If the shining of a thousand Suns blazed forth in the sky, it would be comparable to the Glory of this Great Soul!ï¿½ (chapter 11:12).
Chaitanya told us about this Fire: ï¿½Fire is a functional state of the Consciousness that lives in the Abode of the Creatorï¿½.
Sathya Sai Baba told us the same: ï¿½Fire is not an independently existing state, but that State of Mine, which those Who have cognized Me can see when I enter the world of the Creationï¿½.
The total and steady submerging of the consciousness of a spiritual aspirant into the Divine Fire and mergence with It result in ï¿½burningï¿½ of all remnants of karma. And ï¿½burningï¿½ the body throughout with this Fire brings about the complete healing of the body.
We have to learn to merge with this state of God, by filling His entire form with ourselves as spiritual hearts.
Yet, God does not help everyone in doing this but only His worthy disciples whom He selects.
