The real reason for the enmity between Lord Siva and Daksa is explained here. Daksa was envious of Lord Siva because of Sivas high position as an incarnation of a quality of the Supreme Personality of Godhead and because Siva was directly in contact with the Supersoul and was therefore honored and given a better sitting place than he. There were many other reasons also. Daksa, being materially puffed up, could not tolerate the high position of Lord Siva, so his anger at Lord Sivas not standing up in his presence was only the final manifestation of his envy. Lord Siva is always in meditation and always perceives the Supersoul, as expressed here by the words purusa-buddhi-saksinam. The position of one whose intelligence is always absorbed in meditation upon the Supreme Personality of Godhead is very great and cannot be imitated by anyone, especially an ordinary person. When Daksa entered the arena of yajna, Lord Siva was in meditation and might not have seen Daksa enter, but Daksa took the opportunity to curse him because Daksa had maintained an envious attitude towards Lord Siva for a long time. Those who are actually self-realized see every individual body as a temple of the Supreme Personality of Godhead because the Supreme Personality of Godhead, in His Paramatma feature, is residing in everyones body.
