anubhāvās tu citta-stha- bhāvānām avabodhakāḥ te bahir vikriyā prāyāḥ proktā udbhāsvarākhyayā

The many external ecstatic symptoms or bodily transformations which indicate ecstatic emotions in the mind, and which are also called udbhasvara, are the anubhavas, or subordinate ecstatic expressions of love. Some of these are dancing, falling down and rolling on the ground, singing and crying very loudly, bodily contortions, loud vibrations, yawning, deep breathing, disregard for others, the frothing of saliva, mad laughter, spitting, hiccups and other similar symptoms. All these symptoms are divided into two divisions-sita and ksepana. Singing, yawning and so on are called sita. Dancing and bodily contortions are called ksepana.
