1.2.18 The Two Bhagavats that help a devotee overcome that which is troublesome

What occurs after we become eager to hear, which begins the clearing of material desires from the heart?

naṣṭa-prāyeṣv abhadreṣu

nityaḿ bhāgavata-sevayā

bhagavaty uttama-śloke

bhaktir bhavati naiṣṭhikī

By regular attendance in classes on the Bhāgavatam and by rendering of service to the pure devotee, all that is troublesome to the heart is almost completely destroyed, and loving service unto the Personality of Godhead, who is praised with transcendental songs, is established as an irrevocable fact.

Important Points

A fixed mind can focus

1. In 1.2.17 the anarthas that cause unsteadiness start getting cleared by the Lord's mercy owing to the devotee's increased urge to hear. In 1.2.18 the anarthas that cause unsteadiness are almost completely destroyed . Thus the mind is fixed and can focus. This is the stage of Nistha - almost anartha nivritti. 
2. Main Point: The impediments to bhakti can be removed by service to devotees(person Bhagavata) and Bhagavatam. Thus by hearing and doing service. 
1. The messages of the book Bhagavata have to be received from the devotee Bhagavata, and the combination of these two Bhagavatas will help the neophyte devotee to make progress on and on . (From Unveiling His Lotus Feet - Page 58)
3. Importance of Relationships with devotees(mentioned by Hg Radha Krishna Prabhu while explaining this verse)
1. We avoid association of devotees because we do not want to give up material nature
1. It is impossible to do pure devotional service in association of material nature(therefore do yukta vairagya)
2. Association is important because we hear from the devotees and thus unwanted things leave our heart. Also Krishna is present in their heart.
3. On our own it is hard to grow therefore we must help each other.
4. Good relationships encourages us in service
4. From anartha nivritti you must come to nishtha else something is wrong with your execution.- Hg Radha Krishna Prabhu
