Greetings Gurudev. Paramahansaji told some of his disciples that he felt a hot wave coming from them concluding that they were not suitable for monastic life.What is this hot wave? According to de Broglie we do not possess wavelike properties due to our huge mass.
Think about heat as resistance to the flow of prana (energy) in our nervous system. Heat is a symptom of the nervous system not operating as freely and harmoniously as it should. We know that a wire will heat up if there is resistance when electricity passes through it. Similarly we ‘heat up’ energetically when there is resistance in our nervous system. Heat is a sign of impurities, irritation or imbalance in the flow of energy in the body and brain. This resistance can be from agitated emotions such as anger, negative attitudes, or even impure or agitating foods.
Here is the quote from The New Path by Swami Kriyananda where he relates Yogananda’s comment about experiencing heat from a disciple.
“’Hot!’ he remarked, switching from Boone’s arm to mine. Boone at this time was going through a period of temptations that, alas, ended up taking him off the path.”
You can see from the quote that Yogananda was energetically perceiving resistance within the disciple to teachings and guidance and this resistance eventually took him off the path.
The right attitude for the devotee is calmness and openness to God and Guru. In this way Divine Energy which is always within us can flow freely and we stay ‘cool’ and centered within.
