So here it is said that aghavān. Aghavān means sinful. Agha means sin and vān means... Just like Bhagavān. Bhagavān means one who has bhaga, or opulence, or fortune. That is called bhagavat. And just the opposite is called aghavat.
This is Sanskrit language. Bhagavān means the most opulent, topmost place, Bhagavān. And aghavān means lowest place. So here it is said that one has to become aghavān to the stage of Bhagavān. This is Kṛṣṇa consciousness: not to remain aghavān, but to become Bhagavān. Bhagavān, of course, means the Supreme Personality of Godhead.
But those who are very, very advanced, recognized by Bhagavān, they are also sometimes called Bhagavān. Just like Lord Śiva, Lord Brahma, Nārada Muni, on their status, sometimes they are called Bhagavān. Nowadays it has become a fashion to become Bhagavān.
So Bhagavān is not so cheap. Everyone is aghavān. But if he wants to become Bhagavān or in the higher status, higher level, then it is recommended, "Let him take to the devotional service." Vāsudeve bhagavati bhakti-yoga-prayojitaḥ, janayaty āśu vairāgyam. To become Bhagavān, not Bhagavān but on the level, means highest stage, two things required. One thing is jñāna and one thing is vairāgya. Jñāna and vairāgya.
