Why VATI?!“On the other hand the space is ALL to the practice. I have practiced in a great array of spaces, people's living rooms, prison, schools, zendos, homes of the guru. I have practiced on the beach and in the dirt in Africa. I have practiced in my backyard and in my bedroom. Each of these places can, and have elicited a variance of feeling, at first, to the practice. !!What is noticeable about current yoga practices is that there is a sense of commodity rather than scholarship and spiritual commitment. Contemporary spaces are defined by this misunderstanding of yoga. In order to speak to this mistake, to rectify it in my own practice, I wish to build Vati.!!The space itself will define certain elements of commitment and seriousness combined with joy and serenity. The design should be simple and have great clarity. The materials used to build it should reflect integrity, solidity and craftsmanship.”!!Alice Joanou Clifford !
