“Those things which awaken ecstatic love are called  uddinana  ”
te tu śrī-kṛṣṇa-candrasya 
guṇāś cestāḥ ṇrasādhaṇam
Mainly this awakening is made possible by the qualities and activities of Krṣṇa, as well as by His mode of decoration and the way His hair is arranged.
smitāṅga-saurabhe vaṁśa-śṛṅga-nūpura-kambavaḥ padāṅka-kṣetra-tulasī-bhakta-taḍ-vāṣarādavaḥ
“Kışıña’s smile, the fragrance of His transcendental body, His flute, bugle, ankle bells, conchshell, the marks on His feet, His place of residence, His favorite plant [ tulası ], His devotees, and the observance of fasts and vows connected to His devotion all awaken the symptoms of ecstatic love.”
In  Bhakti-rasāmṛta-sindhu ,  anubhāva  is described as follows:
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  udbhāsvara , are the  anubhāvas , 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— śīta  and  kṣepaṇa . Singing, yawning and so on are called  śīta . Dancing and bodily contortions are called  kṣepaṇa .
The  Bhakti-rasāṃṭa-sindhu  describes  udbhāsvara  as follows:
udbhāsante svadhāmnīti proktā udbhāsvarā budhaiḥ nīvyuttarīya-dhammilla-sraṁsanaṁ gātra-moṭanam jṛmbhā ghrāṇasya phullatvaṁ niśvāsādyāś ca te matāḥ
