desire = karma
I was listening to a lecture series by Bhakti Caitanya Swami (Ten Subjects of Srimad-Bhagavatam). He makes one very interesting point: desire = karma.
If I??(TM)m asked what determines our next body via reincarnation, the usual answer I give is: a mixture of karma and desire. You get what you want according to the amount of ??oebuying power?? you have due to karma. However, as I now realized, the karma is really just another side of the same ??oedesire?? coin. Desire is the root cause of everything.
Any pious activity, which results in good karma and a high quality body, is due to us desiring to perform those activities. By utilizing this stock of good karma, the living entity can then choose its next body from a shelf of high quality bodies, as well as having a sufficiently elevated consciousness to actually desire to inhabitate such a body. Most people (sudras) don??(TM)t actually want to be a CEO (Indra), nor are they qualified to.
