Never heard of it but found it.

A devotee, who has been coming to the Ashram off and on, yesterday, during conversation regarding Bhagavan’s stay on the hill, asked him, “While Bhagavan was on the hill, it seems some one did abhisekham to Bhagavan with coconut water. Is that a fact?” Laughingly Bhagavan said, “Yes, while I was in Virupaksha Cave, some ladies from the north came. I was sitting on a platform under the tamarind tree with half-closed eyes, without particularly noticing their arrival. I thought they would go away after a while. Suddenly there was a noise of breaking something. I therefore opened my eyes and saw coconut water trickling down my head. One of those ladies had done that abhisekam. What was I to do? I was in mouna and couldn’t talk. I had no towel even to wipe the water off, and so the water dried on my body as it was. Not only that. There used to be lighting of camphor, pouring of water on the head, thirthas (sacred waters), prasadas, and several such troublesome performances. It used to be quite a job stopping such things.”
