A leaf, a flower, a fruit, water, whoever offers to Me with bhakti, that, brought with bhakti, I accept from the pure-minded.

न केवलं मद्भक्तानाम् अनावृत्तिलक्षणम् अनन्तफलम् , सुखाराधनश्च अहम् । कथम् ? —
पत्रं पुष्पं फलं तोयम् उदकं यः मे मह्यं भक्त्या प्रयच्छति, तत् अहं पत्रादि भक्त्या उपहृतं भक्तिपूर्वकं प्रापितं भक्त्युपहृतम् अश्नामि गृह्णामि प्रयतात्मनः शुद्धबुद्धेः ॥ २६ ॥
In plain words
It isn't only that My devotees receive an endless fruit — one marked by never having to return to this cycle again. There's more: I am easy to reach through worship. How so? Let's see.
A leaf, a flower, a fruit, water — toya here just means water. Whoever holds it out to me, to me myself, with devotion: that leaf, that whatever-it-is, brought with devotion, reaching me because devotion came first — that is all 'offered-with-devotion' means — I eat it. I take it. From one whose whole self has been made ready, whose understanding has come clear.
Close to the Sanskrit
Not only [is there] endless fruit, characterized by non-return [to rebirth], for My devotees, but I am also easily worshipped. How? —
A leaf, a flower, a fruit, water — toyam, that is, udakam — whoever (yaḥ) offers (prayacchati) to me (me), that is, to me (mahyam), with devotion (bhaktyā): that (tat) I (aham) — the leaf and the rest (patrādi), brought with devotion (bhaktyā upahṛtam), made to reach me with devotion going before it (bhaktipūrvakaṃ prāpitam), that is, 'offered-with-devotion' (bhaktyupahṛtam) — eat (aśnāmi), that is, take (gṛhṇāmi), from one whose self is made ready (prayatātmanaḥ), that is, whose understanding is clear (śuddhabuddheḥ).
