How can devotees engage in charity so that they will not become bound in karma?

From Trivikrama P

Does that mean prabhu that If devotees were to do charity, then that good karma will not bind them? Since you suggested that devotees should do acts of charity(wherever possible, spiritual or material), does it mean that the charity done by devotees will not bind them?
I once heard in H.H. Radhanath Maharaj’s lecture that he suggested that you tell the recipient of the charity to recite ‘Hare Krishna’, then that charity is spiritualized. What should be our consciousness that will make this act of charity spiritual and not bind us?
