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 devotees should be actual examples of cleanliness.
(Srimad Bhagavatam-----7:5:23-24-----purport).

In the Agni Purāṇa it is stated:
vibhāvyate hi raty-ādir yatra yena vibhāvyate
vibhāvo nāma sa dvedhālambanoddīpanātmakaḥ
"That which causes love for Kṛṣṇa to appear is called vibhāva. That has two divisions—ālambana (in which love appears) and uddīpana (by which love appears)."
(Sri Caitanya Caritamrta-----2:23:51-----purport).

In the Agni Purāṇa and other authoritative scriptures, that which increases one's love of Kṛṣṇa is said to be vibhāva, and when Kṛṣṇa is the objective, vibhāva is increased as ālambana. Uddīpana is induced by Kṛṣṇa's transcendental qualities, His activities, His beautiful smiling face and the aroma of His body, the sound of His flute, the sound of His conchshell, the marks on the bottoms of His feet, His dwelling place and His paraphernalia of devotional service (such as tulasī leaves, devotees, ceremonial performances and Ekādaśī). Anubhāva occurs when feelings and emotions within oneself are exhibited. In the attitude of anubhāva, one dances and sometimes falls down, sometimes sings loudly, shows convulsions, yawns, and sometimes breathes very heavily—all without concern for circumstances.
(Teachings of Lord Caitanya).

In the Agni Purāṇa it is stated, "Any person who in gladness sees the worship of the Deity in the temple will obtain the results of kriyā-yoga which are described in the Pañcarātra scripture." Kriyā-yoga is a system of practice much like practical devotional service, but it is especially meant for the mystic yogīs. In other words, by this gradual process the mystic yogīs are eventually elevated to the devotional service of the Lord.
(Nectar of Devotion).

There are eight transcendental symptoms found in the body during ecstasy, and all of them are possible only by a mixture of the above—mentioned five ecstatic divisions. Without some mixture of these five ecstatic principles, one cannot relish transcendental bliss. The cause or basis for relishing transcendental mellow is exactly what we mean by vibhāva. This vibhāva is divided into two—namely, basic and impelling, or impetus—giving. In the Agni Purāṇa the description of vibhāva is given as follows: "The basis from which ecstatic love is born is called vibhāva, which is divided into two-basic and impelling." In other words, there are two kinds of ecstatic love. The object of basic ecstatic love is Kṛṣṇa and His devotee. Lord Kṛṣṇa is the object of basic ecstatic love, and His pure devotee, a reservoir of such love, is the object of impelling ecstatic love. Impelling ecstatic love, then, is that love which develops when one sees an object which reminds him of Kṛṣṇa.
