In some of the Purāṇas the evidence is given that if someone is simply meditating on devotional activities, he has achieved the desired result and has seen face to face the Supreme Personality of Godhead. In this connection, there is a story in the Brahma-vaivarta Purāṇa that in the city of Pratiṣṭhānapura in South India there was once a brāhmaṇa who was not very well-to-do, but who was nevertheless satisfied in himself, thinking that it was because of his past misdeeds and by the desire of Kṛṣṇa that he did not get sufficient money and opulence. So he was not at all sorry for his poor material position, and he used to live very peacefully. He was very openhearted, and sometimes he went to hear some lectures delivered by great realized souls. At one such meeting, while he was very faithfully hearing about Vaiṣṇava activities, he was informed that these activities can be performed even by meditation. In other words, if a person is unable to actually perform Vaiṣṇava activities physically, he can meditate upon the Vaiṣṇava activities and thereby acquire all of the same results. Because the brāhmaṇa was not very well-to-do financially, he decided that he would simply meditate on grand, royal devotional activities, and he began this business thus:
Sometimes he would take his bath in the River Godāvarī. After taking his bath he would sit in a secluded place on the bank of the river, and by practicing the yoga exercises of prāṇāyāma, the usual breathing exercises, he would concentrate his mind. These breathing exercises are meant to mechanically fix the mind upon a particular subject.
