[Due to the unannounced power cut, I could not listen to the remaining portion of the lecture today - 3rd December, 2007. So for the time I will reproduce the Gita sloka 12 with the available comments in a website]
yuktah karma-phalam tyaktva
shantim apnoti naisthikim
phale sakto nibadhyate
"The steadily devoted soul attains unadulterated peace because he offers the result of all activities to Me; whereas a person who is not in union with the Divine, who is greedy for the fruits of his labor, becomes entangled."
