The Panchagni Vidya is very interesting. These are the symptoms of the coming of a time when the body is to be shed. When the impending time comes for passing, the hearing stops. The body and the individuality are constituted of the five elements. The elements withdraw themselves one by one.
Hearing is connected with space.
The divinity of space will withdraw itself and then the hearing stops. A person who is about to die will not hear what one is saying. The next element of descent in the process of creation is Vayu, the touch principle. The tactile sensation ceases. The hearing goes, the sensation also goes.
