“Now I am so advanced that I can kill my guru and I become guru.” Then he’s finished.
Why this Gaudiya Matha failed? Because they tried to become more than guru. He, before passing away, he gave all direction and never said that “This man should be the next acarya.” But these people, just after his passing away they began to fight, who shall be acarya. That is the failure. They never thought, “Why Guru Maharaja gave us instruction so many things, why he did not say that this man should be acarya?” They wanted to create artificially somebody acarya and everything failed. They did not consider even with common sense that if Guru Maharaja wanted to appoint somebody as acarya, why did he not say? He said so many things, and this point he missed? The real point? And they insist upon it. They declared some unfit person to become acarya. Then another man came, then another, acarya, another acarya. So better remain a foolish person perpetually to be directed by Guru Maharaja. That is perfection. And as soon as he learns the Guru Maharaja is dead, “Now I am so advanced that I can kill my guru and I become guru.” Then he’s finished.
