Creation of the Universal Form

PURPORT
As confirmed in  Bhagavad-gītā  (Bg. 4.13), the four orders of human society developed with the order of the body of the gigantic form. The bodily divisions are the mouth, arms, waist and legs. Those who are situated on the mouth are called  brāhmaṇas , those who are situated on the arms are called  kṣatriyas , those who are situated on the waist are called  vaiśyas , and those who are situated on the legs are called  śūdras . Everyone is situated in the body of the Supreme in His gigantic  viśva-rūpa  form. In terms of the four orders, therefore, no caste is to be considered degraded because of being situated on a particular part of the body. In our own bodies we do not show any actual difference in our treatment towards the hands or legs. Each and every part of the body is important, although the mouth is the most important of the bodily parts. If other parts are cut off from the body, a man can continue his life, but if the mouth is cut off, one cannot live. Therefore, this most important part of the body of the Lord is called the sitting place of the  brāhmaṇas , who are inclined to the Vedic wisdom. One who is not inclined to the Vedic wisdom but to mundane affairs cannot be called a  brāhmaṇa , even if he is born of a  brāhmaṇa  family or father. To have a  brāhmaṇa  father does not qualify one as a  brāhmaṇa . The main qualification of a  brāhmaṇa  is to be inclined to the Vedic wisdom. The  Vedas  are situated on the mouth of the Lord, and therefore anyone who is inclined to the Vedic wisdom is certainly situated on the mouth of the Lord, and he is a  brāhmaṇa . This inclination towards Vedic wisdom is also not restricted to any particular caste or community. Anyone from any family and from any part of the world may become inclined to the Vedic wisdom, and that will qualify him as a real  brāhmaṇa .
A real  brāhmaṇa  is the natural teacher or spiritual master. Unless one has Vedic knowledge, one cannot become a spiritual master. The perfect knowledge of the  Vedas  is to know the Lord, the Personality of Godhead, and that is the end of Vedic knowledge, or  Vedānta . One who is situated in the impersonal Brahman and has no information of the Supreme Personality of Godhead may become a  brāhmaṇa , but he cannot become a spiritual master. It is said:  ṣaṭ-karma-nipuṇo vipro mantra-tantra-viśāradaḥ, avaiṣṇava guru asat sat sva-paco vaiṣṇava guruḥ . An impersonalist can become a qualified  brāhmaṇa , but he cannot become a spiritual master unless and until he is promoted to the stage of a Vaiṣṇava, or a devotee of the Personality of Godhead. Lord Caitanya, the great authority of Vedic wisdom in the modern age, stated:
