Prabhupada: Your guru has said that “You chant Hare Krsna, observe these rules.” Do that, don’t speculate, and you will understand everything. No speculation. Do it.

Devotee: Can you explain exactly what speculation means?

Prabhupada: Speculation means thinking, “What will happen? Maybe like this, maybe like this.” That is speculation. [break] …speculate, “Krsna may be like this. Krsna may be like this.” That is speculation. When Krsna appeared before you, you see, “Oh, Krsna is like this.” That is wanted. And if you speculate, “Krsna may be like this,” it is all nonsense. Come to the stage when Krsna will appear before you, and you will see what is Krsna. Be qualified to that position. Mayavadis, they are speculating simply, “God may be like this.” Why “God may be like this”? God is factual, Krsna. Therefore they cannot understand Krsna.
