Krishna and Srila Prabhupada gave us all we need
Three "key" instructions from Srila Prabhupada.
"Before he physically departed, Srila Prabhupada gave us three very important "key" instructions so that we could better understand his unique position and the significance of his Lila. The first key is very simply, "I have given you everything." This means that all his spiritual and personal instruction, lectures, letters, music, art, everything is there, and is enough to get us all back to Godhead. There is no need to add anything.
The second key is, "Do not change anything." This should be clear to everyone, it includes his books, way of performing puja, and his instruction on initiation.
The third key is more difficult for some to understand without knowing and following key one and two. That is, "I will continue to accept disciples and give them my blessings even after I am no longer physically present, you may initiate them on my behalf." To that he added, "I will have millions of disciples", and that any future Guru in the Sampradaya would be called by him, not voted in. Anyone who forgets these three keys will surely be lost and confused..."
