tāńra dainya dekhi' śuni' pāṣāṇa vidare
āmi tuṣṭa hañā tabe kahiluń dońhāre
"uttama hañā hīna kari' mānaha āpanāre
acire karibe kṛṣṇa tomāra uddhāre"
Such are the qualifications of a pure devotee. Materially one may be very opulent, experienced, influential and educated, but if one still thinks himself lower than straw in the street, one attracts the attention of Sri Caitanya Mahaprabhu or Lord Krishna. Although Maharaja Prataparudra was a king, he took up a broom to cleanse the road for Lord Jagannatha's ratha (chariot). Because of this humble service, Sri Caitanya Mahaprabhu was very pleased with the King, and for that reason the Lord embraced him. According to Sri Caitanya Mahaprabhu's instructions, a devotee should never be puffed up by material power. He should know that material power is the result of one's past good activities (karma) and is consequently transient. At any moment all one's material opulence can be finished; therefore a devotee is never proud of such opulence. He is always humble and meek, considering himself lower than a piece of straw. Because of this, the devotees are eligible to return home, back to Godhead.
