It is said in the Hari-bhakti-sudhodaya: "A person who is circumambulating the Deity of Viṣṇu can counteract the circumambulation of repeated birth and death in this material world." The conditioned soul is circumambulating through repeated births and deaths on account of his material existence, and this can be counteracted simply by circumambulating the Deity in the temple.
The Cāturmāsya ceremony is observed during the four months of the rainy season in India, beginning from Śrāvaṇa (approximately July, August, September and October). During these four months, saintly persons who are accustomed to travel from one place to another to propagate Kṛṣṇa consciousness remain at one place, usually a holy place of pilgrimage. During these times, there are certain special rules and regulations which are strictly followed. It is stated in the Skanda Purāṇa that during this period, if someone circumambulates the temple of Viṣṇu at least four times, it is understood that he has traveled all over the universe. By such circumambulation, one is understood to have seen all the holy places where the Ganges water is flowing, and by following the regulative principles of Cāturmāsya one can very quickly be raised to the platform of devotional service.
Arcanā
Arcanā means to worship the Deity in the temple. By executing this process one confirms himself as not body but spirit soul. In the Tenth Canto, 81st Chapter, 16th verse, of the Śrīmad-Bhāgavatam, it is told how Sudāmā, an intimate friend of Kṛṣṇa, while going to the house of a brāhmaṇa murmured to himself, "Simply by worshiping Kṛṣṇa one can easily achieve all the results of heavenly opulence, liberation, supremacy over the planetary systems of the universe, all the opulences of this material world, and the mystic power of performing the yoga system."
The events leading to Sudāmā's murmuring this statement are as follows: Śrī Kṛṣṇa had ordered His friend Sudāmā to go to a brāhmaṇa's house and ask for some food. The brāhmaṇas were performing a great sacrifice, and Śrī Kṛṣṇa told Sudāmā to plead with them that He and Balarāma were feeling hungry and needed some food. When Sudāmā went there, the brāhmaṇas refused to offer anything, but the wives of the brāhmaṇas, upon hearing that Śrī Kṛṣṇa wanted some foodstuff, immediately took many palatable dishes and went to offer them to Śrī Kṛṣṇa. In the Viṣṇu-rahasya also, it is stated: "Any person within this world who is engaged in the worship of Viṣṇu can very easily achieve the ever-blissful kingdom of God, known as Vaikuṇṭha."
