Namaskaram.
I understand about the great part of the Acharyas for the spiritual benefit of the disciples. He also prays to Perumal for the removal of materialistic obstacles for the spiritual elevation of the disciples.
Whether Acharyas (including the present Acharyas) been empowered with any special spiritual power or siddhis, though they may not be using it.
I do not know whether my query is appropriate. Neither I am suspecting about the qualities empowered to them. It just occurred to me and hence, I am posting.
