Srimad Bhagavad Gita -Ramanujacharya

Chapter-4 Jñāna Vibhāga Yogaḥ

Sri Krishna now specifies the cause of His incarnations. yadā yadā hi dharmasya glānir-bhavati bhārata | abhyutthānam-adharmasya tadā’tmānaṃ sṛjāmy-aham || 7 || 7. Whenever there is a decline of Dharma, O Arjuna, and an increase of Adharma, then I incarnate Myself. Commentary There is no restriction as to the time of My birth. Whenever the observance of the Vedic Dharma ordained for the four social categories [intelligentsia, executives, entrepreneurs and workers] according to the four stages of life [student, householder, retiree, renunciate] declines, and its opposite — unrighteousness (Adharma) increases, then I Myself, willingly and in the manner previously stated, incarnate Myself.
