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

This should never be spoken by you to one who lacks austerity, to one without devotion, to one who does not wish to listen, or to one who finds fault with me.

Krishna gives guidance on how this teaching should be shared. It should not be spoken to someone who lacks self-discipline, who has no devotion, who does not wish to listen, or who is hostile to Krishna. The concern is not secrecy for its own sake but readiness. A teaching this demanding can be misunderstood or misused by those who are not open to it. The verse treats the Gita as something to be received with care and respect.
