It is every Sikh's duty to defeat the Five vices: Kam (Lust), Krodh (Rage), Lobh (Greed), Moh (Attachment) and Ahankar (Ego). The Guru Granth Sahib gives clear warning about these plunderers, thus: The Gurmukhs, (Guru oriented) people realise the existence of these five while the Manmukhs (own-mind centred) folks do not and are under the constant exploits of the five - their actions, thoughts and behaviour are totally governed by these negative emotions. They have not learnt to recognise the influence of these negative internal forces and are under their total control.
