The essence of bhakti is:

1) everything  (matter or spirit) belongs to Krishna

2) self (everyone) is part of Krishna

3) self (everyone) is beyond body and matter.

You can give any philosophical conclusion and I can show that it is contained in above 3 statements. If those conclusions are not contained in above 3 statements, then most probably these are not important and can be ignored.  

HpS - AGTSP     The problem I have with your attitude is that as far as I have undestood those who claim to be Krsna's devotees but who have not taken shelter of an Acharya authortzed by Him, are not really His devotees.  They want to be Laksman, or Sita.     The point is not to think but to hear from an Acharya and then do what He says with that knowledge.  This is our position.   It leads us to reject any advise about BG that is not being delivered by the person Parampara. 

Guru teaches us above 3 statements. Krishna from within teaches them. Saints like Vyasa-deva, Gosvamis, Prabhupada,  Bhaiji Hanuman Prasad Poddar, Swami Ramsukh Das etc teach the same statements.

I am trying to realize above statements. That is my qualification. Based on these qualification, I am following Krishna and also, saintly people who are dear to Krishna. I think I am qualified to be initiated based on above qualifications.

My problem with many Iskcon devotees is that they focus on non-relavant topics which don't even affect one's bhakti. Initiation based on these qualification will also show to me that Prabhupada agrees with me. Those topics which don't affect bhakti can be ignored.

I hope Krishna can inspire you from within to see the truth the same way.
