Especially for the householder devotees, the path of Deity worship is strongly recommended. As far as possible, every householder, by the direction of the spiritual master, must install the Deity of Viṣṇu, forms like Rādhā-Kṛṣṇa, Lakṣmī-Nārāyaṇa or Sītā-Rāma especially, or any other form of the Lord, like Nṛsiṁha, Varāha, Gaura-Nitāi, Matsya, Kūrma, śālagrāma-śilā and many other forms of Viṣṇu, like Trivikrama, Keśava, Acyuta, Vāsudeva, Nārāyaṇa and Dāmodara, as recommended in the Vaiṣṇava-tantras or Purāṇas, and one's family should worship strictly following the directions and regulations of arcana-vidhi. Any member of the family who is above twelve years of age should be initiated by a bona fide spiritual master, and all the members of the household should be engaged in the daily service of the Lord, beginning from morning (4 a.m.) till night (10 p.m.) by performing maṅgala-ārātrika, nirañjana, arcana, pūjā, kīrtana, śṛṅgāra, bhoga-vaikāli, sandhyā-ārātrika, pāṭha, bhoga (at night), śayana-ārātrika, etc. Engagement in such worship of the Deity, under the direction of a bona fide spiritual master, will greatly help the householders to purify their very existence and make rapid progress in spiritual knowledge. Simple theoretical book knowledge is not sufficient for a neophyte devotee. Book knowledge is theoretical, whereas the arcana process is practical. Spiritual knowledge must be developed by a combination of theoretical and practical knowledge, and that is the guaranteed way for attainment of spiritual perfection. (Srimad Bhagavatam- 2:3:22-purport).

Severe austerities in the practice of devotional service are of many varieties. For example, in worshiping the Deity in the temple there are certainly laborious activities. Śrī-vigrahārādhana-nitya-nānā śṛṅgāra-tan-mandira-mārjanādau **. One must decorate the Deity, cleanse the temple, bring water from the Ganges and Yamunā, continue the routine work, perform ārati many times, prepare first-class food for the Deity, prepare dresses and so on. In this way, one must constantly be engaged in various activities, and the hard labor involved is certainly an austerity. Similarly, the hard labor involved in preaching, preparing literature, preaching to atheistic men and distributing literature door to door is of course an austerity (tapo-yuktena). Tapo divyaṁ putrakā (S.B.5:5:1). Such austerity is necessary. Yena sattvaṁ śuddhyet. By such austerity in devotional service, one is purified of material existence (kāmān śanair jahau). Indeed, such austerity leads one to the constitutional position of devotional service. In this way one can give up material desires, and as soon as one is freed from material desires, he is free from the repetition of birth and death, old age and disease. (Srimad Bhagavatam-9:4:26-purport).
This is the ideal householder's life. The husband and wife live together, and the husband works very hard to secure paraphernalia for worshiping Lord Viṣṇu. The wife at home cooks a variety of foods for Lord Viṣṇu, and the husband offers it to the Deity. After that, ārati is performed, and the prasādam is distributed amongst family members and guests. According to the Vedic principles, there must always be a guest in a householder's house.
(Sri Caitanya Caritamrta-2:3:41-purport).
