Text 30: O chief of the Kuru dynasty, the Vedic wisdom became manifested from the mouth of the virāṭ, the gigantic form. Those who are inclined to this Vedic knowledge are called brāhmaṇas, and they are the natural teachers and spiritual masters of all the orders of society.
Text 31: Thereafter the power of protection was generated from the arms of the gigantic virāṭ form, and in relation to such power the kṣatriyas also came into existence by following the kṣatriya principle of protecting society from the disturbance of thieves and miscreants.
Text 32: The means of livelihood of all persons, namely production of grains and their distribution to the prajās, was generated from the thighs of the Lord’s gigantic form. The mercantile men who take charge of such execution are called vaiśyas.
Text 33: Thereafter, service was manifested from the legs of the Personality of Godhead for the sake of perfecting the religious function. Situated on the legs are the śūdras, who satisfy the Lord by service.
Text 34: All these different social divisions are born, with their occupational duties and living conditions, from the Supreme Personality of Godhead. Thus for unconditional life and self-realization one has to worship the Supreme Lord under the direction of the spiritual master.
Text 35: O Vidura, who can estimate or measure the transcendental time, work and potency of the gigantic form manifested by the internal potency of the Supreme Personality of Godhead?
Text 36: In spite of my inability, whatever I have been able to hear [from the spiritual master] and whatever I could assimilate I am now describing in glorification of the Lord by pure speech, for otherwise my power of speaking would remain unchaste.
Text 37: The highest perfectional gain of humanity is to engage in discussions of the activities and glories of the Pious Actor. Such activities are so nicely arranged in writing by the greatly learned sages that the actual purpose of the ear is served just by being near them.
Text 38: O my son, the original poet, Brahmā, after mature meditation for one thousand celestial years, could know only that the glories of the Supreme Soul are inconceivable.
Text 39: The wonderful potency of the Supreme Personality of Godhead is bewildering even to the jugglers. That potency is unknown even to the self-sufficient Lord, so it is certainly unknown to others.
Text 40: Words, mind and ego, with their respective controlling demigods, have failed to achieve success in knowing the Supreme Personality of Godhead. Therefore, we simply have to offer our respectful obeisances unto Him as a matter of sanity.
Text 1: Śrī Śukadeva Gosvāmī said: O King, while Maitreya, the great sage, was thus speaking, Vidura, the learned son of Dvaipāyana Vyāsa, expressed a request in a pleasing manner by asking this question.
Text 2: Śrī Vidura said: O great brāhmaṇa, since the Supreme Personality of Godhead is the complete spiritual whole and is unchangeable, how is He connected with the material modes of nature and their activities? If this is His pastime, how do the activities of the unchangeable take place and exhibit qualities without the modes of nature?
