Brāhmaṇa Initiation Lecture — May 25, 1969, New Vrindavan 690525IN-NEW VRINDAVAN [36:48 Minutes] Initiations_690525IN-NEW VRINDAVAN Prabhupāda: ...practically in every initiation ceremony, apavitraḥ pavitro vā, namaḥ [Garuḍa Purāṇa]. [Either pure or impure, or having passed through all conditions of material life, if one can remember the lotus-eyed Kṛṣṇa, he becomes externally and internally clean.] Namaḥ means surrendering. Namāmi: "I surrender unto You. He Kṛṣṇa, I am surrendering to You." And apavitraḥ pavitro vā. Apavitraḥ means contaminated, and pavitra means liberated.
In either stage, either in the material, contaminated stage or in transcendental, liberated stage, apavitraḥ pavitro vā sarvāvasthām, in any situation... Yaḥ smaret puṇḍarīkākṣam. Sarvāvasthāṁ gato 'pi vā. In any circumstances, if somebody remembers, smaret, remembers puṇḍarīkākṣam... Puṇḍarīka akṣam.
Akṣam means eyes. One who is lotus-eyed, Kṛṣṇa or Viṣṇu, puṇḍarīkākṣam, anyone who remembers always or at any time Kṛṣṇa, yaḥ smaret puṇḍarīkākṣam, sa, that person... Bahya. Bahya means externally, and abhyantaram means internally. Bahyābhyantaraṁ śuciḥ. Śuci means brāhmaṇa, or śuci means completely cleansed.
The brāhmaṇa means completely clean. The brahminical qualification is first of all cleanliness. Satya śaucaṁ śamo dama titikṣa ārjavam, jñānaṁ vijñānam āstikyaṁ brahma-karma svabhāva-jam [Bg. 18.42]. [Peacefulness, self-control, austerity, purity, tolerance, honesty, wisdom, knowledge, and religiousness—these are the qualities by which the brāhmaṇas work.] To become brāhmaṇa means satyam saucam. First thing is truthful, and next, śaucam, very cleansed, internally and externally.
Externally we can cleanse ourself by soap and water. That is necessary. Daily we should take bath with soap and water and oil. Bahyābhyantaram.
And abhyantaraṁ śuciḥ means evacuating and cleansing. In yoga system there is a system they practice, they can get out all the intestines and cleanse it clearly. Dhauti. What do they know about this yoga system? They can take out the whole intestine and cleanse it nicely and again set it.
So these are actually practicing yoga system. But who is going to do that? Simply a gymnastic process. So śaucam, cleanliness, is very necessary for advancing in spiritual life. So brāhmaṇa qualification is truthfulness, cleanliness, satyaṁ śaucam.
