(Kadamba Kanana Swami, November 2015, Vrindavan, India, Video Interview)
Karma is the result of getting involved with the material energy for the purpose of enjoyment. When we try to enjoy the material energy, the result is karma – we get reaction for every action. But if we engage that same material energy in the service of Krsna then that same material energy will liberate us and then no more karma will be incurred! So, the key to accumulating karma is trying to enjoy the material energy but freedom from karma comes only from serving Krsna!
