This argument that it is best to not accept any disciples is further explained by Prabhupada in Nectar of Devotion. One should not accept disciples for personal prestige, however, when it comes to increase the Sankirtan movement, things are different in the line of Caitanya Mahaprabhu:
“However, Lord Caitanya’s causeless mercy is such that He advised all bona fide spiritual masters to speak about Krsna consciousness everywhere. Therefore, in the line of Lord Caitanya even the sannyasis can speak about Krsna consciousness everywhere, and if someone is seriously inclined to become a disciple, the sannyasi always accepts him.
The one point is that without increasing the number of disciples, there is no propagation of the cult of Krsna consciousness. Therefore, sometimes even at a risk, a sannyasi in the line of Caitanya Mahaprabhu may accept even a person who is not thoroughly fit to become a disciple. Later on, by the mercy of such a bona fide spiritual master, the disciple is gradually elevated. However, if one increases the number of disciples simply for some prestige or false honor, he will surely fall down in the matter of executing Krsna consciousness.
Similarly, a bona fide spiritual master has no business reading many books simply to show his proficiency or to get popularity by lecturing in different places. One should avoid all these things. It is also stated that a sannyasi should not be enthusiastic about constructing temples. We can see in the lives of various acaryas in the line of Sri Caitanya Mahaprabhu that they are not very enthusiastic about constructing temples. However, if somebody comes forward to offer some service, the same reluctant acaryas will encourage the building of costly temples by such servitors. For example, Rupa Gosvami was offered a favor by Maharaja Mansingh, the commander-in-chief of Emperor Akhbar, and Rupa Gosvami instructed him to construct a large temple for Govindaji, which cost vast amounts of money.”
