Bhagavad Gita, Chapter 18, Verse 67

This is never to be spoken by you to one who is devoid of austerities or devotion, nor to one who does not render service, nor to one who cavils at Me.

Krishna names real limits here on who this teaching should even reach, not everyone is described as ready for it.

This isn't gatekeeping for its own sake, real receptivity is named as a genuine precondition for this knowledge landing well. Care in how something this significant gets shared matters as much as the content itself.
