Very expert at ignoring the mind .

When the Gaudia Vaisnava says you are not the body , he also means you are not the conditioned mind . You can do little about reshaping the material body , the plastic surgeon trys , but you can but Bhakti yoga reshape the mind ..we have two bodies,  the gross physical body and the mental body , both can be employed in devotion to Divinity,  but of the two the mind is the essential. Krishna says in His Bhagavad Gita your mind is your best friend or worse enemy.

The most advanced spiritual devotees develop their mentally conceived spiritual body,  by the practice of purely chanting Gods names , and by smaranam , remembering the name form and pastimes,  then by Dharana ,holding the forms and pastimes in the depths of a spiritually transformed mind , then by Dhyana , entering specific lila , then by Dhruvanasmriti , deep uninterrupted meditations leading to mature Bhava beginnings of love of God .

These processes are the sciences of the change of mind in the Gaudia Vaisnava , Rupa Goswami gives this and more details in his literatures  that Srila AC Bhaktivedanta Swami has translated and commented upon .
