ātmānam api yacchati
kiṁ nv artha-kāmān bhajato
The brāhmaṇa’s wife here implies that since Lord Kṛṣṇa is the ruler of the Bhojas, Vṛṣṇis and Andhakas, if these opulent rulers merely acknowledge Sudāmā as a personal friend of Kṛṣṇa’s, they could give him everything he required.
In this connection Śrīla Viśvanātha Cakravartī comments that since Lord Kṛṣṇa had at this point put aside His weapons, He no longer traveled outside His own capital of Dvārakā. Thus Śrīla Prabhupāda writes in Kṛṣṇa, the Supreme Personality of Godhead: “[The brāhmaṇa’s wife said: ] ‘I have heard that He never leaves His capital city, Dvārakā. He is living there without outside engagements.’”
As mentioned here, material wealth and sense gratification are not very desirable. The reason for this is that in the long run they give no real satisfaction. Still, Sudāmā’s wife thought, even if Sudāmā went to Dvārakā and simply remained silent before the Lord, He would certainly give him abundant wealth, as well as shelter at His lotus feet, which was Sudāmā’s real objective.
