Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Lord showed His lotus feet by raising them. His lotus feet are the source of all awards achieved by devotional service free from material contamination. Such awards are for those who worship Him in pure devotion. The splendor of the transcendental rays from His moonlike toenails and fingernails appeared like the petals of a flower.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Lord fulfills the desires of everyone just as one desires. Pure devotees are interested in achieving the transcendental service of the Lord, which is nondifferent from Him. Therefore, the Lord is the only desire of the pure devotees, and devotional service is the only spotless process for achieving His favor. Srila Rupa Gosvami says in his Bhakti-rasamrta-sindhu (1.1.11) that pure devotional service is jñana-karmady-anavrtam: pure devotional service is without any tinge of speculative knowledge and fruitive activities. Such devotional service is able to award the pure devotee the highest result, namely direct association with the Supreme Personality of Godhead, Lord Krsna. According to the Gopala-tapani Upanisad, the Lord showed one of the many thousands of petals of His lotus feet. It is said: brahmano ’sav anavaratam me dhyatah stutah parardhante so ’budhyata gopa-veso me purastat avirbabhuva. After penetrating for millions of years, Lord Brahma could understand the transcendental form of the Lord as Sri Krsna, in the dress of a cowherd boy, and thus he recorded his experience in the Brahma-samhita in the famous prayer govindam adi-purusam tam aham bhajami.
