At a recent darshan in Desaru a devotee mentioned to Srila Gurudeva that ghosts are disturbing and the devotee is very much disturbed. Below is an insight of the conversation that transpired between the devotee and Srila Gurudeva.
(Devotee): I feel something of someone touching me. I want to know what it is?
(Srila Gurudeva): Are you chanting your rounds?
(Srila Gurudeva) I don't believe. If anyone is chanting and remembering, then no ghost will harm them. Now say after me. 'Om Narasimhaya Namah.'
(Devotee repeats the mantra)
(Srila Gurudeva) You are to say this mantra 3 times. Morning, noon and evening time.
This incident reminded me of Srila Bhaktivinod Thakur when he was a magistrate in Puri. At that time a man who practices the occult was wanting to do the rasa dance with other men's wives and young girls. Srila Bhaktivinod Thakur captured the man and had him thrown in jail. Later Srila Bhaktivinod Thakur experienced severe stomach pains in the night. The next day the man asked Srila Bhaktivinod Thakur whether he felt any pain.
Of course the Thakur was not perturbed by all this. He was chanting throughout the night and nothing could touch him.
There's also another story when Srila Bhaktivinod Thakur had to spend a night in an abandoned temple with his son Bimala Prasad (Srila Bhaktisiddhanta Sarasvati Thakur). There was so much disturbance by a ghost but Srila Bhaktivinod Thakur was chanting throughout the night. The ghost was eventually delivered by our great saint.
Whatever happens, we have to keep on chanting. After all that was the FIRST instruction or order by our Spiritual Master. Then nothing can harm us. We will actually start to develop all good qualities.
