I can say for myself. although being in association of devotees and rendering services of all kinds within ISKCON…and reading Prabhupadas books ……it was not until I heard personally from Srila Gour Govinda Swami…that the messages of Prabhupada and the teachings of our acaryas began to penetrant somewhat and clear understandings began to develop. When Srila Gour Govinda Swami would say ” Give all pleasure to Krishna ” because he lived like that , his messages could penetrate the heart of anyone who wanted to hear . His explanations of Gaura Tattva are  still reverberating around the world as well as all the Tattva’s he so clearly and precisely spoke on with the authority of Sastra that he knew so well , all tattvas of any aspects of Gaudia Vaisnavas were known by him and spoken by him , including the intricacies of all the spiritual truths of the activities of Radha Krishna lila in Vrndavana,  he was truely Radha Dasyam

Srila Bhaktisiddanta Sarasvati Goswami Maharaja…Once heard  Srila Gour Kisore das babaji Maharaja..chant some slokas glorifying Vrsabhanu Nandini, Sri Radhe
So although the Babaji was so called “illiterate.”..Srila Bhaktisiddanta came to understand the Babaji’s highest learning of bhakti rasa ..and Radha dasyam …

So hearing and getting blessings from sadhu guru is vital …the  verse Sadhu sanga sandhu sanga sarva sastra kaya lava matra sadhu sanga sarva siddhi haya gives the importance of pure devotees associated.  Prabhupada gives us that opportunity……after all are we should always understand a pure devotee can make other pure devotees……if he cannot..we could doubt his trancendental potency….

Srila prabhupada Preaching something like this …Verse
By  a former English cricket captain,  who became an active preacher

“Some like to live in the sound of the church and Chapel bell .

I want to run a rescue shop within a yard of hell “

Prabhupada makes everything clear  in his preaching
that what Krishna says is truth , and Prabhupada broadcasts that truth worldwide.

It’s very difficult to find the truth  in a world of crooks .

We live in a multi media shadow world where so called truth appears in many formats …

But the following is the judgement Prabhupada makes ..

na mam duskrtino mudhah
prapadyante naradhamah
mayayapahrta-jnana
asuram bhavam asritah

TRANSLATION

Those miscreants who are grossly foolish, lowest among mankind, whose knowledge is stolen by illusion, and who partake of the atheistic nature of demons, do not surrender unto Me.

Part purport…
Those who are not actually philosophers, scientists, educators, administrators, etc., but who pose themselves as such for material gain, do not accept the plan or path of the Supreme Lord. They have no idea of God; they simply manufacture their own worldly plans and consequently complicate the problems of material existence in their vain attempts to solve them.

So as the English cricket captain said .

As Krishna left Vrndavana to carry out duties,  but always remembers the glorious Radharani and the residents of Vraja , and thus, there is union in separation,
So Srila Prabhupada left Vrndavana to carry out duties,  but anytime he could revert back and engage in deep bhajan , as he did frequently, he was fully absorbed in union in seperation as are his pure followers .
Srimati Radharani Herself, even when sitting on Krishna lap ,can feel extreme separation and call out His name , thus, union and separation are trancendentally equal,  prema vicaita .
