tvaṁ ca ballaba purandarātmaja
tvāṁ ca gokula vareṇya nandini
eṣa mūrdhni racitāñjalir naman
bhikṣate kim api durbhago janaḥ

O Prince of the cowherders (Kṛṣṇa)!
O daughter of the best man of Gokula (Vṛṣabhānu-nandinī Rādhā)!
This unfortunate soul keeps his palms folded on his head and offers his obeisances unto You, begging for something!

BHIKṢĀ PRĀRTHANĀ  (Begging For Alms)

Makaranda Kaṇā Vyākhyā:

In the previous ten verses, Śrīla Rūpa Gosvāmī described the sweetness of Śrī-Śrī Rādhā-Mādhava names, forms, and qualities as They relish Each other. Śrīla Rūpa Gosvāmī is the embodiment of humility, and an ocean of humility wells up in his heart as he speaks these verses and thinks: “O, They are so absorbed in relishing Each others names, forms, scents and qualities, how can a wretch like me possibly experience all these precious things? Does an unfortunate soul like me even have the right to pray for this?”
Although Śrī Rūpa Gosvāmī is an eternally liberated soul, he still considers himself very unfortunate. That is genuine humility.

yenāsādharaṇāśaktādhama buddhiḥ sadātmani
sarvotkarṣānvite’pi syād budhais tad dainyam iṣyate
(Bṛhad Bhāgavatāmṛtam – 2.5.222)

    “That extraordinary attitude, which makes a person always consider himself very unqualified and fallen, although he is actually the most elevated person, is called humility by the wise.” This humble attitude is the culmination of prema.
The example often given is the one of the Vrajasundarīs. They had attained the limit of prema and therefore also the limit of humility.

dainyas tu paramaṁ premnaḥ   paripākeṇa janyate
tāsāṁ gokula nārīṇām  iva Kṛṣṇa viyogataḥ
(Bṛhad Bhāgavatāmṛta – 2.5.224)

    The more one loves Kṛṣṇa as a culmination of humility, the more one becomes anxious to be with Him, to see Him and to serve Him. This eagerness also increases the prema again. In this way eagerness and humility are both vital items of prema.

Śrīpāda Rūpa is a mine of prema, and he is always very agitated by feelings of humility. The ocean of his eagerness wells up with waves of longing as he prays:

“O Nanda-nandana! O Vṛṣabhānu-nandini! Only a person with devotion has the right to pray for Your mercy, but I don’t even have a whiff of devotion! How dare I beg for Your mercy? But then I hear that in Vraja Śrī Nanda Mahārāja and Śrī Vṛṣabhānu Mahārāja are most merciful to the fallen. Indeed, their generosity is widely known throughout Vraja! You are Yourselves oceans of mercy, and You are their children! Therefore, although I am totally unqualified, You cannot let me down! [No one in the world is as merciful and magnanimous to the fallen as Śrī-Śrī Rādhā-Mādhava; nevertheless Śrīpāda humbly considers himself absolutely unqualified for attaining this mercy. Therefore he reminds them of Their descent, in order to get more mercy from Them]
This wretch is therefore keeping his hands folded on his head and is bowing down to Your lotus-feet, begging You for some alms.”

Just as a very hungry beggar anxiously stretches out his hand to receive some food to save his life, Śrī Rūpa Gosvāmī, suffering lethal pangs of separation in the final part of his life, is folding his hands and is praying to his beloved deities in this verse. 

he ballaba purandara,             nandātmaja giridhara,
he śrī Kṛṣṇa sarva rasa kanda.
he gokula vareṇya,             vṛṣabhānu rājakanye,
śrī rādhikā bhānukula candra.
vrajera rajete poḍi,            añjali mastake dhari,
ei hata bhāgya abhājana.
yugalera pādmapadme,           praṇāma koriyā āge,
kichu bhikṣā kore nivedana.

    “O Kṛṣṇa, Giridhārī! O Prince of the cowherders! O source of all rasa! O Princess of Vṛṣabhānu, the best man of Gokula!
O Śrī Rādhikā, moon of Bhānu’s dynasty! This unfortunate wretch falls in the dust of Vraja, folding his hands on his head and offering obeisances to the lotus-feet of the Divine Pair begs for some alms!”
