It is clearly mentioned in this sixth mantra that one should "observe," or systematically see. This means that one must follow the previous ācāryas, the perfected teachers. Anupaśyati is the exact Sanskrit word used in this connection. Anu means "to follow," and paśyati means "to observe." Thus the word anupaśyati means that one should not see things as he does with the naked eye but should follow the previous ācāryas. Due to material defects, the naked eye cannot see anything properly. One cannot see properly unless one has heard from a superior source, and the highest source is the Vedic wisdom, which is spoken by the Lord Himself. Vedic truths are coming in disciplic succession from the Lord to Brahmā, from Brahmā to Nārada, from Nārada to Vyāsa, and from Vyāsa to many of his disciples. Formerly there was no need to record the messages of the Vedas, because people in earlier ages were more intelligent and had sharper memories. They could follow the instructions simply by hearing once from the mouth of a bona fide spiritual master.
At present there are many commentaries on the revealed scriptures, but most of them are not in the line of disciplic succession coming from Śrīla Vyāsadeva, who originally compiled the Vedic wisdom. The final, most perfect and sublime work by Śrīla Vyāsadeva is Śrīmad-Bhāgavatam, which is the natural commentary on the Vedānta-sūtra. There is also the Bhagavad-gītā, which was spoken by the Lord Himself and recorded by Vyāsadeva. These are the most important revealed scriptures, and any
commentary that contradicts the principles of the Bhagavad-gītā or Śrīmad-Bhāgavatam is unauthorized. There is complete agreement among the Upaniṣads, Vedānta-sūtra, Vedas, Bhagavad-gītā and Śrīmad-Bhāgavatam, and no one should try to reach any conclusion about the Vedas without receiving instructions from members of Vyāsadeva's disciplic succession, who believe in the Personality of Godhead and His diverse energies as they are explained in Śrī Īśopaniṣad.
According to the Bhagavad-gītā (18.54), only one who is already on the liberated platform (brahma-bhūta (SB 4.30.20) can become an uttama-adhikārī devotee and see every living being as his own brother. This vision cannot be had by politicians, who are always after some material gain. One who imitates the symptoms of an uttama-adhikārī may serve another's outward body for the purpose of fame or material reward, but he does not serve the spirit soul. Such an imitator can have no information of the spiritual world. The uttama-adhikārī sees the spirit soul within the material body and serves him as spirit. Thus the material aspect is automatically served.
