Bhagavad Gita 8.14

अनन्यचेताः सततं यो मां स्मरति नित्यशः।तस्याहं सुलभः पार्थ नित्ययुक्तस्य योगिनः॥

ananyacetāḥ satataṃ yo māṃ smarati nityaśaḥ |tasyāhaṃ sulabhaḥ pārtha nityayuktasya yoginaḥ ||

I am easily attainable by that ever-steadfast yogi who constantly and daily remembers me for a long time, not thinking of anything else with a single-minded or one-pointed focus, O Partha.

To him who constantly thinks of Me and nothing else, to such an ever-faithful devotee, O Arjuna, I am ever accessible.

Our plain-language meaning of this verse is waiting for scholar review.
