Is ISKCON’s Arcana-paddhati Authorized?

This paper investigates the philosophical and practical standards of arcanā (Deity worship) within the Vaiṣṇava tradition, specifically addressing the apparent contradiction between scriptural authority (śāstra) and the Founder-Ācārya's simplified instructions for his neophyte disciples. The necessity for this harmonization was highlighted by the arguments presented by Suvyakta Narasimha Dāsa in his video, “How the GBC changed Deity worship in ISKCON”. Suvyakta Narasimha Dāsa raises two core objections to the standardized Arcana-paddhati (Deity worship manual) adopted by the institution, claiming they represent deviations from Śrīla Prabhupāda's original system.
Srila Prabhupada at the Center

How can Srila Prabhupada be the center when “the shastra is the center for all”?

Srila Prabhupada says in his purport to Sri Caitanya-caritamrita Madhya-lila 20.352 that among the sources of knowledge of dharma given by one's guru, other saintly persons, and shastra, "the shastra is the center for all." Yet it is seen in many sampradayas that the acharya is still very much central to the practice and faith of the devotees. So, if the actual center is the shastra, then what does it mean to a community to keep the acharya in the center? This video discusses and answers this question.
