There are many historical instances by which we can understand that from kṣatriyas many brāhmaṇas have been born and that from brāhmaṇas many kṣatriyas have been born. The Lord Himself says in Bhagavad-gītā (4.13) , cātur-varṇyaṁ mayā sṛṣṭaṁ guṇa-karma-vibhāgaśaḥ: “According to the three modes of material nature and the work ascribed to them, the four divisions of human society were created by Me.” Therefore, regardless of the family in which one takes birth, when one is qualified with the symptoms of a particular section, he is to be described accordingly. Yal-lakṣaṇaṁ proktam. One’s place in the varṇa divisions of society is determined according to one’s symptoms or qualities. This is maintained everywhere in the śāstra. Birth is a secondary consideration; the first consideration is one’s qualities and activities.
