In the Padma Purāṇa there is a statement about remembering the activities of the Lord: "A person who is always engaged in meditation on the sweet pastimes and wonderful activities of the Lord surely becomes freed from all material contamination."
Meditation on Executing Devotional Service
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 because of his past misdeeds, and by the desire of Kṛṣṇa, 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 thusly:
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 exercise, he would concentrate his mind. This breathing exercise is meant to mechanically make the mind fixed upon a particular subject. That is the result of the breathing exercise and also of the different sitting postures of yoga. Formerly, even quite ordinary persons used to know how to fix the mind upon the remembrance of the Lord, and so the brāhmaṇa was doing this. When he had fixed the form of the Lord in his mind, he began to imagine in his meditations that he was dressing the Lord very nicely in costly clothing, with ornaments, helmets and other paraphernalia. Then he offered his respectful obeisances by bowing down before the Lord. After finishing the dressing he began to imagine that he was cleaning the temple very nicely. After cleansing the temple, he imagined that he had many water jugs made of gold and silver, and he took all those jugs to the river and filled them with the holy water. Not only did he collect water from Godāvarī, but he collected from the Ganges, Yamunā, Narmadā and Kāverī. Generally a Vaiṣṇava, while worshiping the Lord, collects water from all these rivers by mantra chanting. This brāhmaṇa, instead of chanting some mantra, imagined that he was physically securing water from all these rivers in golden and silver water pots. Then he collected all kinds of worshipful paraphernalia—flowers, fruits, incense and sandalwood pulp. He collected everything to place before the Deity. All these waters, flowers and scented articles were then very nicely offered to the Deities to Their satisfaction. Then he offered ārātrika, and with the regulative principles he finished all these activities in the correct worshiping method.
