Whenever an acarya [Spiritual Master] comes, following the superior orders of the Supreme Personality of Godhead or His representative, he establishes the principles of religion, as enunciated in Bhagavad-gita.... Unfortunately, when the acarya disappears, rogues and nondevotees take advantage and immediately begin to introduce unauthorized principles in the name of so-called svamis, yogis, philanthropists, welfare workers and so on….The acarya, the authorized representative of the Supreme Lord, establishes these principles, but when he disappears, things once again become disordered. The perfect disciples of the acarya try to relieve the situation by sincerely following the instructions of the spiritual master….Similarly, a devoted disciple of the spiritual master would rather die with the spiritual master than fail to execute the spiritual master's mission.
