To carry out one's life affairs, one should try his best to conceal his positive points, virtues and blessings so as to prevent other's jealousy. The envious jealousy won't rise unless he sees a blessing in someone.
Therefore, we can enjoy that blessing we have been granted in peace of mind if we conceal it, without letting other's jealousy make that blessing bitter for us. It is not really necessary to constantly talk about our privileges, our virtues to others and brag about the blessings we have been granted. The consequences of this work is making enemies for ourselves and arising others jealousy.
