There are those who mock the actions Chareidim take in the time of need. It is difficult for them to rationalize how spritual prayer can have an affect on the physical body.
Yet not so long ago, there were calls on various news sites to Daven for Rav Eliashiv, Rav Matisyahu Salomon and Rav Y. Belsky.
Rav Eliashiv has been reported to be doing better, Rav Matisyahu's hospital stay was quick, and now Rav Belsky has been released from 3 months of "hospitality".
In addition to the Tallis, Tefillah, Tefillin and Tehillim, I wonder if Rav Belsky was zoche to have his body repaired in the merit of his teaching about Hilchos Treifos for so many years?
