Vishnu and Brahma split their ways downwards and upwards respectively to find the end of the light in either directions. Brahma lied that he discovered the end of the pillar in his direction, while Vishnu conceded his defeat. Shiva cursed Brahma that he would have no place in ceremonies while Vishnu would be worshipped till the end of eternity.
To find the end of light, Vishnu and Brahma explored in opposite directions. Brahma falsely declared he discovered the end of his pillar, whereas Vishnu admitted defeat. Consequently, Shiva cursed Brahma's exclusion from ceremonies while ensuring Vishnu's enduring worship.
