śrī-śuka uvāca
evaṁ bhagavatā rājan
 śrīvatsāṅkena sat-kṛtaḥ
āmantrya taṁ parikramya
 sagaṇaḥ svālayaṁ yayau
Word for word: 
śrī-śukaḥ uvāca — Śrī Śukadeva Gosvāmī said; evam — thus; bhagavatā — by the Supreme Personality of Godhead; rājan — O King; śrīvatsa-aṅkena — who always carries the mark of Śrīvatsa on His breast; sat-kṛtaḥ — being very much applauded; āmantrya — taking permission from; tam — Him; parikramya — circumambulating; sa-gaṇaḥ — with his associates; sva-ālayam — to his own abode; yayau — went back.
Translation: 
Śukadeva Gosvāmī said: O King, having thus been praised by the Supreme Personality, who bears the mark of Śrīvatsa on His chest, Lord Śiva circumambulated Him. Then, after taking permission from Him, Lord Śiva returned to his abode, Kailāsa, along with his associates.
Purport: 

Śrīla Viśvanātha Cakravartī Ṭhākura remarks that when Lord Śiva was offering obeisances unto Lord Viṣṇu, Lord Viṣṇu arose and embraced him. Therefore the word śrīvatsāṅkena is used here. The mark of Śrīvatsa adorns the chest of Lord Viṣṇu, and therefore when Lord Viṣṇu embraced Lord Śiva while being circumambulated, the Śrīvatsa mark touched Lord Śiva’s bosom.
