Whenever an acharya 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. Religion means abiding by the orders of the Supreme Personality of Godhead. Religious principles begin from the time one surrenders to the Supreme Personality of Godhead. It is the acharya's duty to spread a bona fide religious system and induce everyone to bow down before the Supreme Lord. One executes the religious principles by rendering devotional service, specifically the nine items like hearing, chanting and remembering. Unfortunately, when the acharya 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. Actually, human life is meant for executing the orders of the Supreme Lord, and this is stated in Bhagavad-gita (9.34):
man-mana bhava mad-bhakto
mad-yaji mam namaskuru
mam evaishyasi yuktvaivam
atmanam mat-parayanah
"Engage your mind always in thinking of Me and become My devotee. Offer obeisances and worship Me. Being completely absorbed in Me, surely you will come to Me."
The main business of human society is to think of the Supreme Personality of Godhead at all times, to become His devotees, to worship the Supreme Lord and to bow down before Him. The acharya, the authorized
representative of the Supreme Lord, establishes these principles, but
when he disappears, things once again become disordered. The perfect
disciples of the acharya try to relieve the situation by
sincerely following the instructions of the spiritual master. At the
present moment practically the entire world is afraid of rogues and
nondevotees; therefore this Krishna consciousness movement is started
to save the world from irreligious principles. Everyone should
cooperate with this movement in order to bring about actual peace and
happiness in the world.
...A devoted disciple of the spiritual master would rather die with the
spiritual master than fail to execute the spiritual master's mission.
As the Supreme Personality of Godhead comes down upon this earth to
reestablish the principles of religion, so His representative, the
spiritual master, also comes to reestablish religious principles. It is
the duty of the disciples to take charge of the mission of the
spiritual master and execute it properly. Otherwise the disciple should
decide to die along with the spiritual master. In other words, to
execute the will of the spiritual master, the disciple should be
prepared to lay down his life and abandon all personal considerations.
