According to Osho, while past karma and samskaras condition you, they don’t imprison you absolutely: one leg is tied, one is free. Present awareness and choice remain within your control—use them to act opposite to conditioning, transform arising impulses (like anger), and dissolve habits. Consciousness is free; the future is your freedom to break chains you created.
You can’t change your past, but right now you can notice your habits and choose differently, slowly undoing them.
