Namaskaram Swami! Srimathe Ramanujaya Namah! Sri Sriranga Narayana Jeeyar Swamigale Saranam! Sri Velukkudi Krishnan Swamigal Thriuvadigale Saranam! 

In Srimad Bhagavatam 10 Canto 89th chapter, the narration ends with Bhrgu Muni kicking Perumal’s chest and Perumal reacting humbly, thus proving that Perumal is the most qualified to receive the avir bhagam. 

Swami, please guide us to the reference in Puranas or scriptures (exact verses) for the following part:

After Bhrgu Muni kicks Perumal’s chest, Thayaar gets insulted as it’s her abode and leaves for planet Earth. In pursuit of Thayaar, Perumal also comes to the Earth from His abode in Karya Vaikuntha. Thus, He appears as Lord Balaji / Venkateswara.

adiyen,

Badrinarayana Ramanuja Dasan.
