I hope you will not misunderstand the position of the Acarya who is so important a figure in the matter of learning the transcendental science. The Acarya is the direct representative of the Personality of Godhead. And no body can claim to become a bona fide Acarya if he has not strictly followed the footprints of the previous Acaryas authorized in the matter. The whole thing has been disturbed in the set of Sanatana Dharma only by violating this principle of following the Acarya. So far the Bhagawat Geeta is concerned every one, let him be a very great scholar in the mundane sense, must be in confirmed position along with the mode of understanding of Shri Arjuna. That is the crucial point of testing an Acarya false or real Shri Arjuna is the first man to understand Geeta and the mode of his understanding is clearly defined in the Bhagawat Geeta. So there is no difficulty in testing an Acarya whether he is false or bona fide.
Our determination is to preach the Bhagawat Geeta strictly on that parampara system as it is recommended in the Bhagawat Geeta.
In the last portion of the Bhagawat Geeta the necessary qualification of understanding the Bhagawat Geeta is clearly stated.
According to this formula of qualification one who does not accept Krishna as the Supreme Personality of Godhead—is unable to understand the Bhagawat Geeta.
