tribhir vihīnaṁ yam anantam ṛṣayaḥ
na veda siddhārtham iva kvacit sthitaṁ
The incarnation of the Supreme Personality of Godhead known as Śeṣa or Ananta has unlimited strength, fame, wealth, knowledge, beauty and renunciation. As described in this verse, Ananta’s strength is so great that the innumerable universes rest on His hoods. He has the bodily features of a snake with thousands of hoods, and since His strength is unlimited, all the universes resting on His hoods feel no heavier than mustard seeds. We can just imagine how insignificant a mustard seed is on the hood of a serpent. In this connection, the reader is referred to Śrī Caitanya-caritāmṛta, Ādi-līlā, Chapter Five, verses 117-125. There it is stated that Lord Viṣṇu’s incarnation as the serpentine Ananta Śeṣa Nāga supports all the universes on His hoods. By our calculation, a universe may be very, very heavy, but because the Lord is ananta (unlimited), He feels the weight to be no heavier than a mustard seed.
