Srila Prabhupada passtimes: 37-Even if you are seventy percent Krishna conscious, still Krishna will take you.

Jayapataka Swami : 

Once Srila Prabhupada was giving a lecture about how we have to be cent percent Krishna conscious. He was ramming home the point that we have to surrender to Krishna one hundred percent. At the end of the class the devotees were serious. They were looking down thinking, "Who can come up to the standard of complete surrender?" As if he could read their minds, Prabhupada relaxed his mood a little bit and said, "If you can be ninety percent Krishna conscious, then you can also go back to Godhead." 

He was on a large, high vyasasana, four feet in the air, and had to go down some steps to get off the vyasasana. As he started down he said, "Even if you are eighty percent surrendered, Krishna will still take you." 

Then he got off the vyasasana and started walking away. His chaddar was flowing behind him, dragging on the ground. He stopped, looked at the devotees and said, "Even if you are seventy percent Krishna conscious, still Krishna will take you." He threw his chaddar over his shoulder and walked off with his head high.
