Unsalted rice

Hello friends,
So I am a Taichi practitioner, and for a year I had an issue opening my middle split. My Sifu gave me a recommendation to make unsalted rice every morning and eat. And in two weeks I will have my results. He said I have to leave rice in water overnight and then cook it until it becomes jelly-like.
What do you think about this? How does it work, if it does at all?
Thank you!
