Mutra (urine) is derived during the course of biological processes within the human body. The first stage of urine formation begins in the large intestine where fluids are absorbed into the system. The entire urinary system (kidneys, uterus, bladder and urethra) takes part in the formation and elimination of urine, regulating the fluid balance in our body and also maintaining blood pressure. Any imbalance of increased or decreased urine may result in disorders as kidney stones urinary infections, cystitis, abdominal pain and bladder disorders.
Sweda (sweat) is the third primary Mala, and it occurs as a waste product during the synthesis of meda Dhatu (fatty tissue). Eliminated through skin pores, it controls body temperature and helps to regulate the electrolytic balance. The channels responsible for bringing the sweat to skin surface are known as sweda vaha srotas. It is essential that normal formation and flow of sweat takes place as otherwise it may lead to skin infections, itching/burning sensation over the body, loss of fluid balance and reduced body temperature.
The Mala (Excretion) of food is faeces and urine. Rasa (juices, fluid) excretion is Kapha (mucus, phlegm, spit), that of Rakt (blood) is Pitta (bile), Medas (fat) excretion is sweat, that of Asthi (bones) is hair in head and body that of Majja(marrow) is fat in joints. Thus the fractions of essence and excretion formed during the process of metabolism support each other and thus maintain the body by mutual coordination.
Never try to hold any these Malas forcibly. Whenever urges occur, try to go to the toilet. Otherwise, it may cause serious diseases.
Balanced Doshas (humors), healthy Agni, a good state of tissues and their metabolic end- products lead to a balanced state of the senses, mind and spirit, all of which lead to health.
