Vishnu's roopa/beauty and his avatar is none other than Shiva. In other words, Shiva is Vishnu. The one in Shiva roopa is none other than Vishnu. In other words, Vishnu is Shiva! Vishnu resides in Shiva's heart & Shiva resides in Vishnu's heart. Vishnu will be found in the same place you find Shiva and Shiva can be found in the same place Vishnu is.

"Shivaaya Vishnu Roopaaya Shiva Roopaaya Vishanave 
Shivasya Hrudayam Vishnur Vishnuscha Hrudayam Shivaha 
Yatha Shivamayo Vishnuhu Yevam Vishnu Mayaha Shivaha 
Yathaantharam Na Paschyaami Thatha Me Swasthi Ra Yushi"

Vishnu resides in Shiva's heart & Shiva resides in Vishnu's heart. Vishnu will be found in the same place you find Shiva and Shiva can be found in the same place Vishnu is.‪ As is if you find one, you have found the other. We are one and the same.! This mantra/sloka is found in the yajurveda. It can also be found towards the end of the yajurveda sandhyavanam. Shiva meditates on Rama Nama, he worships Ram which is another roopa of Vishnu. "Sri Rama Rama Rameti, Rame Raame Manorame, Sahasra Naam Tat Tulyam, Rama Naam Varanane" Lord Shiva says to Parvati, I chant the holy name of Rama, this holy name of Rama is equal to one thousand holy names of Lord Vishnu!!
