Gautama said I have conquered Heaven and Earth by the help of selfcontrol. For my considering all creatures and objects impartially, I am like a smokeless fire. Hence I am incapable of being subjugated by you. When, again, I was born, the effulgence of my body removed the surrounding darkness. For these reasons I am called Gautama.
गौतम उवाच गोदमो दमतोऽधूमोऽदमस्ते समदर्शनात्। विद्धि मां गौतमं कृत्ये यातुधानि निबोध माम्॥
