Vishnu Purana in 6.5.74 states:
"ऐश्वर्यस्य समग्रस्य धर्मस्य यशसरिश्रयः।
ज्ञानवैराग्ययोश्चैव षण्णां भग इतीरणा ।।"
Complete splendor, virtue, glory, opulence, knowledge, dispassion - these six are known as bhaga.
One who possess these Bhaga quality is known as Bhagavan. And the following verses after it identify Bhagavan as Vãsudeva or Lord Vishnu. Thus from this we can know Lord Vishnu Possesses six Auspicious qualities (Kalyana Guna). The same Paragraph continues stating:
The purport of the letter va is that elemental spirit in which all beings exist, and which exists in all beings. And thus this great word Bhagavan is the name of Vásudeva, who is one with the supreme Brahma, and of no one else. This word therefore, which is the general denomination of an adorable object, is not used in reference to the supreme in a general, but a special signification. (Vishnu Purana 6.5)
