vision. But in your case I think you can wait for the vision to develop of itself or at any rate leave it till later. For you what is important to carry on what has begun till it is complete in all the parts of your nature.Sri Aurobindo

Sri Aurobindo — Sahana Devi
February 28, 1932
We do not consider it necessary for you to practice tratak. It may be useful for some who have a strong predisposition ― in Dilip for instance, in his development something was always trying to bring out this power of vision. But in your case I think you can wait for the vision to develop of itself or at any rate leave it till later. For you what is important to carry on what has begun till it is complete in all the parts of your nature.
P.S. It is not necessary for you to go on teaching P ― as she is learning elsewhere.
