Great to read your thoughts on karma. The Sanskrit text Bhagavad Gita talks a lot about karma. I have heard it described that we only have miniscule free will. All we can do is desire, and the rest is done, not by us but by the laws of nature.

Apparently even good karma is still karma and obliges you to return in the next life to receive the rewards. However, the goal is to eradicate all karma so that you don't have to return at all and can go back to godhead, so to speak. We can do this by stopping all mundane work or action (Karma means work/action in Sanskrit). Instead we engage in non-karma producing activity, which means pure bhakti yoga or action in divine consciousness in service to the divine, not to our mundane senses. Service to the divine, in the form of meditation, chanting the names, worship or some sort, is all karma-free, and transcendental. All other action is karmic and obliges a rebirth.
