According to Osho, there should be no secrecy about kundalini and the chakras today—recording is fine. What remains 'secret' depends on humanity’s readiness: some truths were withheld in Buddha’s time to prevent harm, not from ignorance. As consciousness evolves, more can be shared; disclosure should match the seeker’s maturity.
We can share and write about these things now, but only as much as people are ready to handle safely and wisely.
