Mental Infidelity

Hi,

On the concept of mental infidelity:

"The Torah states (Bamidbar 15), 'And you shall not stray after your hearts.'

"Based on this, Rebbe taught: One may not drink from one cup while he turns his eyes toward another." [I think the euphemism is obvious.]

(Talmud, Nedarim 20b)

Have a great day,
Mordechai
