So long we are in this material encagement we are supposed to be impurified. Because we are not purified, therefore we have to accept birth, death, old age and disease. Just like diseased condition is impurified. It requires to be purified by medical treatment so get out of the disease. So we living entities, we are part and parcel of God. Our original position is purified, but at the present moment we are contaminated. So by chanting the holy name of the Lord we become purified. The holy name of the Lord and the Lord, identical. By association with the Supreme Lord directly, by chanting the holy name, we become purified. Oṁ apavitraḥ pavitro vā sarvāvasthāṁ gato 'pi vā, yaḥ smaret puṇḍarīkākṣam (Garuḍa Purāṇa). Kṛṣṇa, His name is Puṇḍarīkākṣaṁ. Puṇḍarīka means lotus flower; akṣam means eyes—whose eyes are just like the lotus flower. Lord Visnu, or Kṛṣṇa, is identified with lotus flower in so many places. His navel is like lotus flower, His eyes are like lotus flower, His feet, lotus feet. So lotus is the comparison of the beauty of different limbs or parts of the body, transcendental body of Kṛṣṇa.
So those who are going to be initiated, they should understand that chanting of the holy name means directly associating with the Supreme Lord. So as I have given several times the example of the iron rod and the fire—if you touch the iron rod with the fire, it becomes warmer, warmer and then red hot—similarly, when you chant offenselessly the holy name of the Lord, gradually you become purified, and when we chant holy name without any offense, then we immediately live at the shelter of Lord Kṛṣṇa. When we are almost free from contamination, then we become liberated, and when we chant purely the holy name, we are situated on the lotus feet of the Lord. And the more we go on chanting, we enjoy loving exchange affair between the Lord and ourself.
