Something to exercise on, a limited number of Yoga Mats are supplied but if you have your own Yoga Mat then please feel free to bring it, otherwise, a rug or something similar is perfectly suitable. (Kundalini Yoga is traditionally practiced on a sheep’s skin)
If you are new to Yoga or think you may have trouble with your flexibility then bring a small cushion.
A blanket is a nice option to have for the relaxation.
A water bottle is a good idea, it can be filled up at the kitchen.
Wear loose, comfortable clothing.
Most importantly bring yourself and an attitude to become happy, healthy and whole!
