The expression iron in fire was used several times by the founder of ISKCON AC Bhaktivedanta Swami Prabhupada and can be understood in many ways.

It’s not so easy to place an iron bar in the middle of a fire and keep it  in position amongst the energies and turbulence of a  raging inferno .

In devotional terms, the science of how the cold iron turns into fire is elaborately described by Rupa Goswami, and the process of how to initiate it is given by Prahlada Maharaja.

The graduation of heat exchanges depends on a number of circumstances, which are also clearly laid out by Srila Ragganatha das Goswami .

A very quick transformation is possible,  but the fire has to stay burning strongly, and the iron kept  firmly in the centre ground .

Someone may say iron is iron fire is fire and will doubt the whole concept.

But one would say ” touch the iron ” ……it will act like fire .

Thus, the pure spiritual personality has revived his spiritual form , by the nine fold processes  , they have undergone the process of removing all  obstacles , and are  in a  fixed position , they feel the intense  heat , and many other transformation take place within their spiritual minds  as if becomes fully embraced and absorbed in the activities of the spiritual kingdom. Such a person  is fully able to transfer the heat of  his devotional rasa that he feels into another person , faith carries one a long way , but one must know the scientific process and understand the perfection of it .
