Sometimes these big leaders take up the guise of a sannyasi and call themselves mahatmas, but their only business is conquering their political enemies
SB Canto 5
There were and are many political and social heroes who have conquered enemies of equal power, yet due to their ignorance in believing that the land is theirs, they fight one another and lay down their lives in battle. They are not able to take up the spiritual path accepted by those in the renounced order. Although they are big heroes and political leaders, they cannot take to the path of spiritual realization.
Big political leaders might be able to conquer equally powerful political enemies, but unfortunately they cannot subdue their strong senses, the enemies that always accompany them. Not being able to conquer these nearby enemies, they simply try to conquer other enemies, and ultimately they die in the struggle for existence. They do not take to the path of spiritual realization or become sannyāsīs. Sometimes these big leaders take up the guise of a sannyāsī and call themselves mahātmās, but their only business is conquering their political enemies. Because they spoil their lives with the illusion of "this is my land and my family," they cannot progress spiritually and attain liberation from the clutches of māyā.
