I am going to pass on the Pranayama.
Basti
This can be practiced with or without a bamboo tube. But it is better to have a bamboo-tube. Sit in a tub of water covering your navel. Assume the posture Utkatasana by resting your body on the forepart of your feet, the heels pressing against the posteriors. Take a small bamboo-tube 6 fingers long and insert 4 fingers of its length into the anus after lubricating the tube with vaseline or soap or castor oil. Then contract the anus. Draw the water into the bowels slowly. Shake well the water within the bowels and then expel the water outside. It is known as Jala-Basti.
