Will is neither part of mind nor part of being. It is a bridge. It is just like a grass floating on your ocean called ‘mind’. Neither you can use will to control mind nor vice-versa. You can only increase the frequency of the being which reduces the strength of the mind. This is the only way. 

Being is the land or earth, ocean is the mind, will is the piece of straw lying were ocean meets the land. 

Increase the land.
