#keeping one's

Pious persons, the devout sikhs, instinctively honour their words at all costs, they do not trample over it, rather they fulfill it. 

When someone goes back upon his word, it must be assumed, he made the commitment on account of ego or to deceive somebody.

Such a person makes false promises to another, to make some unfair gains, on account of being avaricious, but dishonours it, afterwards, on weighing the pros and cons related to it. Selfishness, glamour and lustre of wealth are always found to be the dominant factors, behind the commitments, which are nor honoured.
