Your left energy channel (called Ida nadi in Sanskrit), also known as the moon channel, begins at the Mooladhara chakra and travels up the left side of your body, terminating in the superego area on the right side of your mind-brain. The superego is the storehouse of all your memories, habits and conditionings. Your superego is also the area of your brain that encourages moral behavior. In most of us, it has to wage war on our more selfish, pleasure seeking urges in the process.
Joy is an essential quality associated with the left energy channel.
Ideally, it is felt as the innocent joy of a child. Remember when you were a young child and you’d wake up happy every morning? The joy carried by the left energy channel feels just like that. As adults, we long for this joy, though we don’t often find it. It may become blocked or “bruised” by some of our life experiences. However, it still lives within us and can be awakened through meditation.
If you have a problem with your left energy channel, you may experience emotional extremes. This includes moods that shift rapidly from elation to depression and back again. You may also experience lethargy and extreme passivity. Most of us have suffered the occasional “couch potato” day. Remember the lack of energy and desire you felt as you sat around, doing nothing at all? That feeling may have been caused by a problem with your left energy channel.
In summary, your left energy channel influences your emotions, feelings and desires.
It is also connected to your memories and past experiences. As long as your emotions stay at normal levels, you’ll do just fine. However, if you’re feeling extremes of emotion such as depression, gloominess and brooding, then it’s time to do something about it.
All you need to start clearing your left channel is meditation. Sahaja Yoga techniques are easy, safe and the renewed feelings of joy and energy you’ll experience can be positively addictive.
