The only purpose of mind is to chant the holy names, so it is always under one's control.
The intelligence will do the rest from the instructions of paramatma and the vedic scriptures ,spiritually and from the right guidance,materially.
The ego becomes true ego when one engages in service of Krsna ,Guru,Gauranga ,Vaishnavas so that one knows their position as a servant of the servant of Lord.
True emotions come from the soul and spiritualised consciousness, that of love ,compassion, empathy, thus one has to neglect the idea of one is a body or one is a mind.
This is my basic reflection from lectures I have heard. I'm not sure if I'm completely right.Please may I know if there is any faulty learning.
