Tirukkural 108: Virtue of Gratitude

It is not good to forget a benefit; it is good to forget an injury even in the very moment (in which it is inflicted)

There is in much of the world the belief that life is a burden, a feeling of penitence, that it is good to suffer, good for the soul. In fact, spiritual life is not that way at all.
