Our sense of smell is our most primitive sense, and is the first sense that awakens upon our physical birth. The receptors for smell are located at the base of our brain and feeds directly into our limbic system, which is the area of memory and emotion. Therefore, aromas can immediately access emotional memories stored in our unconscious.
The Sanskrit name for it is "Muladhara" and it's Sanskrit translation is "Root Support".
Strengthening the ChakraEdit
Walking is one of the best excersises for this chakra. Choose places with beauty and fresh air to take long walks. Start with low, gentle walks. Then, as your fitness improves, increase your pace and the length of your stride. Also you should carry some water and a high energy snack if you plan on walking further than usual. Don't forget to take in the beauty of the surroundings.
