Thank you for sharing this with us happymillionaire.
The funny thing is, it is really never "too late." Even if their body has physically deteriorated to a point it cannot regenerate, the healing that can happen emotionally, mentally, and spiritually is well worth the effort, even if they only have a limited time left to be here physically. And even now, Chunyi would say you can send energy to your Mother to make her transition easier and prepare her for her next circle of life. A simple thing would be to see her (yourself, and any others you'd wish to bring in), in the ball while doing the joining of yin and yang, being energized and healed with the energy, as you are.
Much Love,
Shawn
