Is Lord Balaji the same as Lord Krishna, or is he Vishnu?

Is Lord Balaji the same as Lord Krishna, or is he Vishnu? Yes, in Kali Yuga Lord Krishna manifested as Lord Venkateshwara or Balaji. This is because during Dwapara Yuga, Yashoda complains to Lord Krishna that she was not able to witness anyone of his marriages. So to please her, in Kali Yuga Krishna manifested as Venkateshwara and Yashodha reborn as Vakula devi and with her help Lord Venkateshwara married Padmavathi Devi who is an incarnation of Goddess Lakshmi. Om Namo Narayana
