What is explained in brief in the earlier sutta quotes is explained in detail at...MN 148: Chachakka Suttahttp://www.accesstoinsight.org/tipitaka ... .than.html
The whole sutta is relevant (I guess that goes without saying), but if you want to get to the section specific to your question, scroll down to the part that says "Now, this is the path of practice leading to the cessation of self-identification."
That the compilers of the Sutta Pitaka saw fit to mention that "while this explanation was being given, the hearts of 60 monks, through no clinging, were fully released from fermentation/effluents" is testament to the regard in which the instruction was held.
"Do not force others, including children, by any means whatsoever, to adopt your views, whether by authority, threat, money, propaganda, or even education." - Ven. Thich Nhat Hanh
"The uprooting of identity is seen by the noble ones as pleasurable; but this contradicts what the whole world sees." (Snp 3.12)
"To argue with a person who has renounced the use of reason is like administering medicine to the dead" - Thomas Paine
