BE AMBIDEXTROUS! Use both 🙏 hands and see what happens 😲 

If you perform certain gym exercises only exercising the right side (if you're a righty)...as an experiment, you'll notice a twist in your walk, stance, gait, and soon, the effect will echo into your organs and nerves and soon you will become prone to injuries more often. Try to not listen to music, or see nature, light, abstract ideas and just keep performing math and logic based actions for years together in a dark room... I hope you get my point in general.

The left hand is considered to be the path of Dakshin/south bound and opposite to the direction of the guru who resides in the north and so none except a guru must perform dhyana and gives instructions while facing the south; all others must face north or it signifies great disrespect and arrogance to dare assume the position of a teacher. The left hand is tantric, is sometimes looked down upon but more so in India. It is the path of aghoris and occultists, witches and powerful magicians, the left nadi Ida represents the moon, hidden things, occult, deceit and shady behaviour, the sun nadi, Pingala is the leader, goodness, transparency, illumination, warmth, rational and all good things/auspicious activities must be undertaken using the right hand for the results will be God like and not devilish (so is the belief. I think use both, both are made by God/divinity..whatever; but I don't force anyone to remain right-handed. Out of respect for tradition and the teachings of BKS Iyengar, I don't use the left hand for pranayama, though I did for almost 4 years and decided not to). There is also another explanation with reflects regressive and ignorant beliefs, such as the left hand representing untouchables and to be used only to clean unclean areas of the body - it is a very caste oriented, backward and elitist outlook that must be shunned as we are living in the illuminated age of science; however, the left hand still represents devilish activities and symbolically, we don't use it for example, digitally controlled breathing unless you have seriously injured your right hand.
