What Exactly Is The Refuah For Corona? [#14893]

The Rav has said that the remedy for coronavirus is to access “ayin” [lit. “nothingness”, to negate one’s sense of self) and on a deeper level, to feel “efes” [lit. “zero”, to feel absolute nothingness of all physical reality]. I want to understand this better. I have understood from the Rav that a person can actually get a refuah for corona by adhering to the above advice. Baruch Hashem this question is not relevant to me or even to anyone related to me, but I am asking this question with regards to the rest of Klal Yisrael, and the Rav’s answer to this will probably be of immeasurable benefit to anyone. After all, who’s not interested in knowing the refuah for corona!! This is what I would like to know:
(1) When the Rav says that the refuah for corona is “ayin” (nothingness), does this mean negating one’s sense of self, or having mesirus nefesh (being self-sacrificing? Or by having emunah (faith in G-d)? And when the Rav says that a deeper method of refuah for corona is to access the power of “efes”, does this mean to think about Ain Od Milvado (there is nothing besides for Hashem)? And how can a person sick with corona practically use the above advice?

1) [In the terms of Kaballah], Keser is ayin (feeling a sense of nothingness), and this divides into two spiritual dimensions (Partzufin) of Atik and Arikh. The lower aspect of Keser corresponds to Arikh, or ayin (nothingness, no sense of self), and the higher aspect of Keser corresponds to Atik, or efes (absolute nothingness). A temporary remedy [for corona] is through accessing ayin (feeling a sense of nothingness, by having mesirus nefesh, self-effacement), but in order to get the complete remedy [for corona] which will totally uproot the disease from the person, is only through accessing the level of efes (contemplating “Ain Od Milvado, efes Zulaso, lit. “There is nothing besides for Him, there is zero except for Him.”)
