In his Deivamani Malai, Saint Vallalar says that there are seven qualities that keep us from reaching God.
Kama, or desire, is the first of these. Desire can lead us down the wrong paths.
Anger is the next sin that Vallalar talks of. The mean man, who cannot bring himself to give to others, is also a sinner. Laziness, ego and envy come next in the list. He who does not hesitate to harm others is a great sinner, says Vallalar, and prays that those with such qualities should not approach him.
Allied to these seven categories of sinners are those who lack sympathy for others, those who are vengeful and those who indulge in self pity.
