Bhagavad Gita Chapter 8
Powerful Cognition
The people who reach Krishna are those who remain continuously on the path of yoga, continuously fixed upon the Divine without deviation throughout their life.
ananyacetāḥ satataṃ yo māṃ smarati nityaśaḥ tasyāhaṃ sulabhaḥ pārtha nityayuktasya yoginaḥ
I am always available to anyone who remembers Me constantly Pārtha, because of his constant engagement in devotional service.
