According to Osho, no—you did not earn this by past-life merit; the very notion springs from egoic doership. The Gita teaches prasad, grace: what is essential is given, unasked. True merit flowers as humility—'I did nothing; I am blessed.' Clinging to accounts of virtue blocks the way to God; drop the doer and receive.
Listening to the Gita isn't your achievement; it's a gift—let go of pride and just receive.
