Srimad Bhagavatam Canto 11, Chapter 27, Text 15

SB 11.27.15

dravyaih prasiddhair mad-yagah
 pratimadisv amayinah
bhaktasya ca yatha-labdhair
 hrdi bhavena caiva hi
 
Translation: 
 
One should worship Me in My Deity forms by offering the most excellent paraphernalia. But a devotee completely freed from material desire may worship Me with whatever he is able to obtain, and may even worship Me within his heart with mental paraphernalia.
 
Purport: 
 
A devotee still troubled by material desire tends to see the world as an object of sense gratification. Such a neophyte devotee may misunderstand the Lord’s supreme position and may even consider the Lord an object of his own enjoyment. Hence the neophyte must offer opulent paraphernalia to the Deity so that he may constantly remember that the Deity is the supreme enjoyer and that he, the neophyte, is simply the worshiper and is actually meant for the Deity’s pleasure. In contrast, an advanced devotee, one fixed in Krsna consciousness, never forgets that the Supreme Lord is the actual enjoyer and controller of everything. The pure devotee offers his unalloyed love to the Personality of Godhead along with whatever paraphernalia is easily obtained. A Krsna conscious devotee does not waver in his devotion to Lord Krsna, and even with the simplest offering he completely satisfies the Personality of Godhead.
