Vishnu sahasranamam, slok31

Slok31:        AmruthamsuDbhavo  BhAnuhu  SasibinDuhu  Sureswaraha
                      OwshaDham  jagathaha  sethuhu  Sathya Dharma Parakramaha

The  ocean born Nector (Amruth ),  the Sun,  the Moon, a bestower of Water,  the Lord of Gods, the complete plantation on earth, ,  the Universal connectivity,  the Truth, the Rightuousness, the 
Valour, is sree maha Vishnu.

Vishnu is the ultimate Truth. The absolute Righteousness.
"Ramo Sathyavan  Dharmavan Vigrahaha"  was the emblem of Lord " Sree Rama " . Lord Vishnu manifested as Sree Rama , with this emblem.  Hence it is automatically implied that

Sree Rama is a resemblence of Vishnu. This aspect is emphasised in this slok.

Sun and Moon pocess the Devine Radiation of Lord Vishnu. These two are not sheer planets, they are  considered as" Visible Vishnu".

Moon is cause of water and plantation on earth.  Whereas, Sun is the cause of vitality and growth. Life on Earth is directly depending on Sun and Moon. This is how we are connected to Vishnu.

The Universal Mind, Vishnu is connecting the entire universe invisibly.

What to leave , what to say??  In this universe , Vishnu's presence is everywhere in everything.

Vishnu is the Eswara of both Sura and Nara .
