Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 29-30

Sanskrit:

आत्मतुल्यै: षोडशभिर्विना श्रीवत्सकौस्तुभौ ।पर्युपासितमुन्निद्रशरदम्बुरुहेक्षणम् ॥ २९ ॥द‍ृष्ट्वा तमवनौ सर्व ईक्षणाह्लादविक्लवा: ।दण्डवत् पतिता राजञ्छनैरुत्थाय तुष्टुवु: ॥ ३० ॥

ITRANS:

ātma-tulyaiḥ ṣoḍaśabhirvinā śrīvatsa-kaustubhauparyupāsitam unnidra-śarad-amburuhekṣaṇam

Translation:

Surrounding and serving the Supreme Personality of Godhead, Nārāyaṇa, were sixteen personal attendants, decorated with ornaments and appearing exactly like Him but without the mark of Śrīvatsa and the Kaustubha jewel. O King, when all the demigods saw the Supreme Lord in that posture, smiling with eyes like the petals of lotuses grown in autumn, they were overwhelmed with happiness and immediately fell down like rods, offering daṇḍavats. Then they slowly rose and pleased the Lord by offering Him prayers.

Purport:

In Vaikuṇṭhaloka the Supreme Personality of Godhead has four hands and decorations like the Śrīvatsa mark on His chest and the gem known as Kaustubha. These are special indications of the Supreme Personality of Godhead. The Lord’s personal attendants and other devotees in Vaikuṇṭha have the same features, except for the Śrīvatsa mark and the Kaustubha gem.
