One has to be qualified to preach. It is a gradual process that one becomes sense controlled and a personal example. Preaching is not an easy thing. In the beginning one should worship the Deity and follow the basic practices. When one becomes advanced he can preach. The kanistha adhikari is not condemned. It is a comparative study. The kanistha adhikari can also achieve perfection. If one does not preach, it does not mean that he is fallen, condemned. It is not artificial, one gradually becomes perfect by association.
It is correct that the brahma-jyotir is comprised of spiritual souls and that ultimately nothing is impersonal. Dead matter means forgetfulness of Krsna.
If you want to stay in Krsna Consciousness you will have to develop firm faith in Guru and Sastra. Therefore, you must study my books very scrutinizingly, follow the four regulative principles very strictly and chant 16 rounds daily avoiding the ten offenses. Don't take this movement as something cheap.
