Srimad Bhagavatam Canto 04, Chapter 30, Text 28

SB 4.30.28

etavat tvam hi vibhubhir
 bhavyam dinesu vatsalaih
yad anusmaryate kale
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
Dear Lord, You are the killer of all inauspicious things. You are compassionate upon Your poor devotees through the expansion of Your arca-vigraha. You should certainly think of us as Your eternal servants.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
The form of the Lord known as arca-vigraha is an expansion of His unlimited potencies. When the Lord is gradually satisfied with the service of a devotee, in due course of time He accepts the devotee as one of His many unalloyed servants. By nature, the Lord is very compassionate; therefore the service of neophyte devotees is accepted by the Lord. As confirmed in Bhagavad-gita (9.26):
patram puspam phalam toyam
 yo me bhaktya prayacchati
tad aham bhakty-upahrtam
 asnami prayatatmanah
“If one offers Me with love and devotion a leaf, a flower, fruit or water, I will accept it.” The devotee offers eatables in the form of vegetables, fruits, leaves and water to the arca-vigraha. The Lord, being bhakta-vatsala, compassionate upon His devotees, accepts these offerings. Atheists may think that the devotees are engaged in idol worship, but the fact is different. Janardana, the Supreme Lord, accepts bhava, the attitude of service. The neophyte devotee engaged in the worship of the Lord may not understand the value of such worship, but the Supreme Lord, being bhakta-vatsala, accepts His devotee and in due course of time takes him home.
In this connection there is a story about a brahmana who was offering sweet rice to the Lord within his mind. The brahmana had no money nor any means of worshiping the Deity, but within his mind he arranged everything nicely. He had gold pots to bring water from the sacred rivers to wash the Deity, and he offered the Deity very sumptuous food, including sweet rice. Once, before he offered the sweet rice, he thought that it was too hot, and he thought, “Oh, let me test it. My, it is very hot.” When he put his finger in the sweet rice to test it, his finger was burned and his meditation broken. Although he was offering food to the Lord within his mind, the Lord accepted it nonetheless. Consequently, the Lord in Vaikuntha immediately sent a chariot to bring the brahmana back home, back to Godhead. Thus it is the duty of every sincere devotee to accept the arca-vigraha at home or in the temple and worship the form of the Lord as advised in authorized scriptures and directed by the spiritual master.
