Haumai, literally "I-I", or I-am-ness, is the Sikh term for the ego-centred condition that Guru Nanak identifies as the fundamental human problem. It is not pride in the ordinary sense but the deeper structure of self-reference out of which pride and the other faults grow: the assumption that one is a separate centre with its own claims, around which reality ought to arrange itself.
The Guru Granth Sahib describes it in strikingly clinical language. Haumai is called a chronic disease, and in a much-cited passage the scripture says that haumai is a deep affliction but that within it lies its own remedy, if grace is granted, one acts according to the Guru's word and is healed. The formulation matters. The cure is not the suppression of the self by effort, which the tradition regards as simply another operation of the ego, but a reorientation that comes through the Guru and by grace.
Haumai is the root of the five thieves, lust, anger, greed, attachment and pride, and it is what keeps a person a manmukh and bound to transmigration. Its opposite is not self-abasement, which the tradition treats as a further form of self-preoccupation, but the dissolution of the boundary altogether, described in the scripture through the images of the drop and the ocean and of the wall of falsehood broken down.
The teaching has a distinctive practical consequence. Because haumai attaches itself to religious achievement as readily as to worldly success, Sikh scripture is unusually sharp about ostentatious piety, ritual performance and asceticism: the yogi's austerities and the brahmin's observances are criticised on precisely this ground, that they feed the very thing they claim to remove, and that the ascetic who has renounced the world may be more thoroughly self-occupied than the householder who has not. And because the remedy is the Name, remembrance in the middle of ordinary work and family life is presented as more effective than withdrawal, which the tradition treats as a way of protecting the ego rather than dissolving it.
