I have said many times that there is no difference between the speech of the Protector Nagarjuna, and the speech of the Buddha. Nagarjuna says in one verse that of all the kinds of wealth, the wealth of contentment is the best. Even if you have no material wealth you are wealthy when you have contentment. With contentment you have the absolute, perfect, supreme wealth. So what these lines say is extremely important.
Contentment comes with being satisfied with what one has.
One doesn't feel that one has to accumulate many things, or have things of extremely good quality. If one has contentment one doesn't have those kinds of grasping feeling. In general we should think about how extremely fortunate we are. Even though we do not have a lot of jewels decorating our heads and bodies as nagas do, we have a precious human rebirth which has the eight leisures and ten good-fortunes. Because we have these eight leisures and ten fortunes we have the opportunity to practise dharma.
