by His Divine Grace A.C. Bhaktivedanta Swami Prabhupada:
There are many pseudo-worshipers who become religionists only for the sake of name and fame. Such pseudo-religionists do not wish to get out of this universe and reach the spiritual sky. They only want to maintain the status quo in the material world under the garb of worshiping the Lord.
The atheists and impersonalists, by preaching the cult of atheism, lead such foolish pseudo-religionists into the darkest regions. The atheist directly denies the existence of the Supreme Personality of Godhead, and the impersonalists support the atheists by stressing the impersonal aspect of the Supreme Lord….
The pseudo-religionists have neither knowledge nor detachment from material affairs, for most of them want to live in the golden shackles of material bondage under the shadow of philanthropic activities disguised as religious principles. By a false display of religious sentiments, they present a show of devotional service while indulging in all sorts of immoral activities. In this way, they pass as spiritual masters and devotees of God. Such violators of religious principles have no respect for the authoritative ācāryas, the holy teachers in the strict disciplic succession. They ignore the Vedic injunction ācāryopāsanā — “One must worship the ācārya.” — and Krishna’s statement in the Bhagavad-gītā (4.2) evam paramparā-prāptam — “This supreme science of God is received through the disciplic succession.” Instead, to mislead the people in general, they themselves become so-called ācāryas. But they do not even follow the principles of the ācāryas.
These rogues are the most dangerous elements in human society. Because there is no religious government to prohibit such things, they escape punishment. They cannot, however, escape the law of the Supreme, who has clearly declared in the Bhagavad-gītā that envious demons in the garb of religious propagandists shall be thrown into the darkest regions of hell.(Bg. 16.19-20) Śrī Īśopanisad confirms that these pseudo-religionists are heading toward the most obnoxious place in the universe after the completion of their spiritual master business, which they conduct simply for sense gratification.
