Upendra: Swamijī, someone approached me and we were discussing about Kṛṣṇa consciousness. And I said to approach Kṛṣṇa one must be pure, but he said, "What is purity?" Could you explain that technically? What is purity?
Prabhupāda: Yes. Purity means standing on the spiritual platform. That is purity. In the material platform there is no purity. So according to Bhagavad-gītā, that standard of purity, that means standing on the spiritual platform, which is called brahma-bhūtaḥ. Brahma-bhūtaḥ. So Kṛṣṇa says this purity,
- māṁ ca vyabhicāreṇa
- bhakti-yogena yaḥ sevate
- sa guṇān samatītyaitān
- brahma-bhūyāya kalpate
- (BG 14.26)
This Brahman understanding, or to stand on the Brahman platform, is purity. How one can attain that platform of purity? Kṛṣṇa says that "One who is engaged in devotional service to Me without any deviation," that means twenty-four hours in Kṛṣṇa consciousness, "he is pure." He is pure. If you can keep yourself always, constantly in Kṛṣṇa consciousness, always thinking of Kṛṣṇa, then you are pure. Otherwise... Kṛṣṇa consciousness or God consciousness, it doesn't make any difference. So just like if you keep always in touch with fire you are warm—there is no possibility of being cold—similarly, some way or other if you always keep yourself in Kṛṣṇa consciousness or God consciousness, then you are pure. Therefore we advise our students, "Chant Hare Kṛṣṇa." As soon as you chant this sound, Kṛṣṇa, immediately you are in touch with Kṛṣṇa. Therefore you are, you keep yourself pure. Is that clear? Yes. So try to keep yourself in Kṛṣṇa consciousness without any deviation. Then you remain pure.
