Bhagavad Gita
Chapter 9 · Verse 22
अनन्याश्चिन्तयन्तो मां ये जनाः पर्युपासते। तेषां नित्याभियुक्तानां योगक्षेमं वहाम्यहम्॥
ananyāś cintayanto māṁ ye janāḥ paryupāsate, teṣāṁ nityābhiyuktānāṁ yoga-kṣemaṁ vahāmy aham
A verse about steady, wholehearted focus being met with support: the sense that what's genuinely needed tends to arrive.
What you truly need has a way of arriving when your focus is whole.
