Srimad-Bhagavatam: Canto 11 - Chapter 1 - Verse 16-17

Sanskrit:

स्‍नानालङ्करणं प्रेष्ठमर्चायामेव तूद्धव ।स्थण्डिले तत्त्वविन्यासो वह्नावाज्यप्लुतं हवि: ॥ १६ ॥सूर्ये चाभ्यर्हणं प्रेष्ठं सलिले सलिलादिभि: ।श्रद्धयोपाहृतं प्रेष्ठं भक्तेन मम वार्यपि ॥ १७ ॥

ITRANS:

snānālaṅkaraṇaṁ preṣṭhamarcāyām eva tūddhavasthaṇḍile tattva-vinyāsovahnāv ājya-plutaṁ haviḥ

Translation:

In worshiping the temple Deity, my dear Uddhava, bathing and decoration are the most pleasing offerings. For the Deity traced on sacred ground, the process of tattva-vinyāsa is most dear. Oblations of sesame and barley soaked in ghee are the preferred offering to the sacrificial fire, whereas worship consisting of upasthāna and arghya is preferred for the sun. One should worship Me in the form of water by offering water itself. Actually, whatever is offered to Me with faith by My devotee — even if only a little water — is most dear to Me.

Purport:

The Supreme Personality of Godhead is present everywhere, and Vedic culture prescribes various ritualistic methods for worshiping the Lord in His various manifestations. The principal item is the faith and devotion of the worshiper, without which everything else is useless, as the Lord describes in the next verse.
