Gṛhastha devotees must adopt the arcana-vidhi, or Deity worship according to the suitable arrangements and directions given by the spiritual master. Regarding those unable to take to the Deity worship in the temple, there is the following statement in the Agni Purāṇa. Any householder devotee circumstantially unable to worship the Deity must at least see the Deity worship, and in this way he may achieve success also. The special purpose of Deity worship is to keep oneself always pure and clean. Gṛhastha devoteesshould be actual examples of cleanliness.
(Srimad Bhagavatam-----7:5:23-24-----purport).

Deity worship should be continued along with hearing and chanting. Therefore every mantra is preceded by the word namaḥ. In all the mantras there are specific potencies, of which the gṛhastha devotees must take advantage. There are many mantras preceded by the word namaḥ, but if one chants the holy name of the Lord, he receives the result of chanting namaḥ many times. By chanting the holy name of the Lord, one can reach the platform of love of Godhead. One might ask, then what is the necessity of being initiated? The answer is that even though the chanting of the holy name is sufficient to enable one to progress in spiritual life to the standard of love of Godhead, one is nonetheless susceptible to contamination because of possessing a material body. Consequently, special stress is given to the arcana-vidhi. One should therefore regularly take advantage of both the bhāgavata process and pāñcarātrikī process.
(Srimad Bhagavatam-----7:5:23-24-----purport).

Aside from this, if a gṛhastha devotee worships the śālagrāma-śilā, or the form of the Deity at home, his home also becomes a very great place. It was therefore customary for members of the three higher classes—namely the brāhmaṇas, kṣatriyas and vaiśyas—to worship the śālagrāma-śilā, or a small Deity of Rādhā-Kṛṣṇa or Sītā-Rāma in each and every home. This made everything auspicious. But now they have given up the Deity worship. Men have become modernized and are consequently indulging in all sorts of sinful activities, and therefore they are extremely unhappy.
(Srimad Bhagavatam-----7:14:29-----purport).

A viṣayī is one who is attached to family life and is interested only in wife, children and worldly sense gratification. The senses can be engaged either in worldly enjoyment or in the service of the Lord. Those who are not engaged in the service of the Lord and are interested only in material sense gratification are called viṣayī. Śrīla Rāmānanda Rāya was engaged in government service, and he belonged to the karaṇa class. He was certainly not a sannyāsī in saffron cloth, yet he was in the transcendental position of a paramahaṁsa householder. Before becoming Caitanya Mahāprabhu's disciple, Sārvabhauma Bhaṭṭācārya considered Rāmānanda Rāya an ordinary viṣayī because he was a householder engaged in government service. However, when the Bhaṭṭācārya was actually enlightened in Vaiṣṇava philosophy, he could understand the exalted transcendental position of Śrī Rāmānanda Rāya; therefore he referred to him as adhikārī. An adhikārī is one who knows the transcendental science of Kṛṣṇa and is engaged in His service; therefore all gṛhastha devotees are designated as dāsa adhikārī.
