 SB 4.28.48

uttisthottistha rajarse
 imam udadhi-mekhalam
dasyubhyah ksatra-bandhubhyo
 bibhyatim patum arhasi
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
O best of kings, please get up! Get up! Just see this world surrounded by water and infested with rogues and so-called kings. This world is very much afraid, and it is your duty to protect her.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Whenever an acarya 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 acarya’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 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. 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 evaisyasi 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 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. At the present moment practically the entire world is afraid of rogues and nondevotees; therefore this Krsna 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.
