udbhāsante svadhāmnīti proktā udbhāsvarā budhaiḥ nīvyuttarīya-dhammilla- sraṁsanaṁ gātra-moṭanam jṛmbhā ghrāṇasya phullatvaṁ niśvāsādyāś ca te matāḥ

The ecstatic symptoms manifest in the external body of a person in ecstatic love are called by learned scholars udbhasvara. Some of these are a slackening of the belt and a dropping of clothes and hair. Others are bodily contortions, yawning, a trembling of the front portion of the nostrils, heavy breathing, hiccupping and falling down and rolling on the ground. These are the external manifestations of emotional love. Stambha and other symptoms are described in Madhya-lila (14.167).
