What are the signs of a hypocrite?

Imam As-Sadiq (a.s.) said:
Luqman said to his son:
“لِمُنافِقِ ثَلاثُ عَلامات: يُخَالِفُ لِسانُهُ قَلْبَهُ وَ قَلْبُهُ فِعْلَهُ وَ عَلانِيَتُهُ سَرِيْرَتَهُ”

Translation
There are three signs of the hypocrites: their tongue is not consistent with their heart, nor their heart with their deed, nor their outward with their inward.1

Brief Description
Hypocrisy is a painful, loathsome trait originating from low personality and weak will. To make themselves look better than they are, their tongues will tell a different story from what is in their hearts, they will not walk their talk, will not practice what they preach. They are a weak people, afraid to reveal their true selves, lacking the will and determination to improve themselves. They appear in different garbs and are treacherous with everybody, even themselves. Even more dangerous are the societies that display a good looking exterior but have bad, rotting, interior. Their tongue and the mass media, is in stark contrast with what is going on in the heart of these societies.[divider]
