"In whatever condition one may be, either unclean or clean," yaḥ, "anyone who," smaret, "remembers," puṇḍarīkākṣam... Puṇḍarīkākṣam means Kṛṣṇa. Kṛṣṇa's another name is puṇḍarīkākṣam. Yaḥ smaret puṇḍarīkākṣam, sa: "That person," bahya, "externally," abhyantaram, "internally," śuciḥ, "becomes at once purified." Śrī-viṣṇu śrī-viṣṇu śrī-viṣṇu. Puṇḍarīkākṣam, Kṛṣṇa or Viṣṇu.
