The purport of this mantra is that if anyone is impure, apavitraḥ . . . pavitraḥ means pure. Anyone, either he is pure or impure, it doesn't matter. Apavitraḥ pavitraḥ vā sarvāvasthām. In any condition of life, it doesn't matter. Pure or impure, there are two conditions. Someone is impure, someone is pure. So either way, namo apavitraḥ pavitro, sarvāvasthām, in any condition, yaḥ smaret puṇḍarīkākṣam: anyone who remembers puṇḍarīkākṣam, means Viṣṇu or Kṛṣṇa . . .
Yaḥ smaret puṇḍarīkākṣaṁ sa, that person, bahyābhyantaraṁ śuciḥ, he immediately becomes cleansed inside and outside. Śuciḥ, śuciḥ means clean or śuciḥ means brāhmin. Brāhmin means clean. You have got all threads, so you should always prove that you are always clean. Bahyābhyantaraṁ śuciḥ. Śrī Viṣṇu śrī viṣṇu śrī viṣṇu. So this is remembering Viṣṇu.
So simply by remembering Viṣṇu, if one becomes clean inside and outside, so by chanting Hare Kṛṣṇa, how much purified he is becoming in every moment or every second. It is so nice. There is no question if we always keep ourselves chanting Hare Kṛṣṇa, Hare Kṛṣṇa, Kṛṣṇa Kṛṣṇa, Hare Hare/ Hare Rāma, Hare Rāma, Rāma Rāma, Hare Hare, so there is no chance of being contaminated by the influence of māyā. It is so nice.
