PURPORT

It appears that Advaita Acarya had two different houses, one at Santipura and one at Navadvipa. When Lord Caitanya Mahaprabhu was born, Advaita Acarya was residing not at His Navadvipa house but at His Santipura house. Therefore, as formerly explained, "nijalaya," from Advaita's old paternal house in Santipura, Sita came to Navadvipa to present gifts to the newly born child, Caitanya Mahaprabhu.
