Symptoms of an acarya

1. Lord Caitanya Mahaprabhu wanted to invent a way to capture the Mayavadis and others who did not take interest in the Krsna consciousness movement. This is the symptom of an acarya. An acarya who comes for the service of the Lord cannot be expected to conform to a stereotype, for he must find the ways and means by which Krsna consciousness may be spread.
2. Sri Caitanya Mahaprabhu was an ideal acarya. An acarya is an ideal teacher who knows the purport of the revealed scriptures, behaves exactly according to their injunctions and teaches his students to adopt these principles also.
3.  As an ideal acarya, Sri Caitanya Mahaprabhu devised ways to capture all kinds of atheists and materialists. Every acarya has a specific means of propagating his spiritual movement with the aim of bringing men to Krsna consciousness. Therefore, the method of one acarya may be different from that of another, but the ultimate goal is never neglected.  
4. Srila Rupa Gosvami recommends:
1. tasmat kenapy upayena manah krsne nivesayet
   sarve vidhi-nisedhah syur etayor eva kinkarah
2. An acarya should devise a means by which people may somehow or other come to Krsna consciousness.
3.  First they should become Krsna conscious, and all the prescribed rules and regulations may later gradually be introduced. In our Krsna consciousness movement we follow this policy of Lord Sri Caitanya Mahaprabhu.
4.  For example, since boys and girls in the Western countries freely intermingle, special concessions regarding their customs and habits are necessary to bring them to Krsna consciousness.
5.  The acarya must devise a means to bring them to devotional service. 
6. Therefore, although I am a sannyasi I sometimes take part in getting boys and girls married, although in the history of sannyasa no sannyasi has personally taken part in marrying his disciples.
