If we chant Hare Kṛṣṇa mantra, then we come to our perfection. At the present moment, we are illusioned. Just like every one of us thinking that "I am this body." Otherwise, why there is so much fighting? Everyone is thinking, "I am this body." This bodily concept of life is māyā, illusion, or ignorance. So the whole process is to drive away the ignorance. Drive away. That is called jñāna. We are in the ajñāna.
- ajñāna-timirāndhasya
- jñānāñjana-śalākayā
- cakṣur unmīlitaṁ yena
- tasmai śrī-gurave namaḥ
Every one of us is covered by the darkness of ajñāna. What is that ajñāna? "I am this body." "I am Indian." "I am American." "I am Andhra," "I am Bengali." "I am this, I am that." So there is fighting, due to ajñāna. So first of all we have to drive away this ajñāna. Therefore Kṛṣṇa is teaching Arjuna that "You are not this body. You are spirit soul." This is the first spiritual instruction by the authority to anyone, that "You are not this body." So by chanting Hare Kṛṣṇa mantra... It is the medicine recommended in the śāstra, ceto-darpaṇa-mārjanam (CC Antya 20.12). That dust of ignorance is moved. He can understand that "I am not this body; I am spirit soul, part and parcel of Kṛṣṇa. My duty is to serve Kṛṣṇa." In this way, he becomes enlightened gradually.
