Text 18] Deliverance of the Yamala-arjuna Trees

by their association more than a rich man does. Because Nārada Muni, in his previous life, was the poverty-stricken son of a maidservant, he got the association of saintly persons and later became the exalted Nārada Muni. This was his actual experience. Therefore, he is now comparing the position of a poor man with that of a rich man.
satāṁ prasaṅgān mama vīrya-saṁvido bhavanti hṛt-karṇa-rasāyanāḥ kathāḥ taj-joṣaṇād āśv apavarga-vartmani śraddhā ratir bhaktir anukramiṣyati (Bhāg. 3.25.25)
If one gets the advantage of association with saintly persons, by their instructions one becomes more and more purified of material desires.
kṛṣṇa-bahirmukha haiyā bhoga-vāñchā kare nikaṭa-stha māyā tāre jāpaṭiyā dhare (Prema-vivarta)
Material life means that one forgets Kṛṣṇa and that one increases in one's desires for sense gratification. But if one receives the advantage of instructions from saintly persons and forgets the importance of material desires, one is automatically purified.  Ceto-darpaṇa-mārjanaṁ bhava-mahādāvāgni-nirvāpaṇam (Śikṣāṣṭaka 1).  Unless the core of a materialistic person's heart is purified, he cannot get rid of the pangs of  bhava-mahādāvāgni , the blazing fire of material existence.
