A link to the hespedim of Rav Moshe Twersky ztz"l Hy"d at the conclusion of the shiva here. You can believe everything all of the maspidim say except where HaGaon Rav Dovid Cohen Shlita the Rosh Yeshiva of Chevron says [in his humility] that he is in the captivity of his yetzer hara. Believe me sweet friends - I am in captivity, most people I know are in captivity - but he Shlita is NOT:-).
May we all be zoche to go free - ואין בן חורין אלא מי שעוסק בתלמוד תורה!!
I thank my beloved friend and sometimes "email chavrusa", R' Meir Zev Steinmetz, for the link.
