Tons of Sandballs each weighing a ton

Of late, there have been tons of sandballs flying all around me. No where to run, no where to hide. Only to dig my legs into the ground and hold my root while practicing taiji. All is well so far, thanks in no small part to my good Masters from Shinnyo-en who have taught me solid leg and foot work. However, my shoulders and waist ache from all the taijiing. Hopefully with such training, my skills can grow and I would finally be able to taiji the big balls of sand effortlessly without sustaining any major injuries.

With faith.
With strength.
With heart.
