6 months ago, I published detailed analysis how an ISKCON sannyasi travels on three continents with young unmarried female russian translator.
In that same article, we even obtained reply by Indradyumna Swami, where he says it is ok that she travels with him, because she is only “russian translator, nothing more, nothing less”.
This actually establishes important shift in Prabhupada’s mission. Now, sannyasis can have transcendental, service related relationships with women. This is the essence of sahajiya philosophy, than a man can step beyond the level of renunciation, and although he already renounced association of opposite sex, he is now renouncing the renunciation itself.
