What is the most important lesson the scriptures teach us

The shastras (scriptures) direct and counsel everyone. People yield to delusion and become one with the darkness caused by false values and attachment to the unreal - the “me” and “mine”. But scripture is the mother; she does not give up. She persists and pursues; she reminds people of their goal in order to ensure that they will be saved. One need not drink the entire ocean to know its taste; placing just one drop on the tongue is enough. Similarly, it is impossible to understand all the contents of the scriptures. It is enough if one grasps the important lesson that is elaborated therein and puts that lesson into practice. The lesson is: Constant thought of God.
