It is not safe while you are doing the yoga another influence,whatever it may be, which is not ours or part of the movement of this sadhana. If that takes place anything might happen and we would not be able to protect you against it because you would have stepped out of the circle of protection. A diversion of this kind which seems to be on the vital level might be a serious interference. No trust can be put on the beauty of the eyes or the face. There are many Beings of the inferior planes who have a captivating beauty and can enthral with it and they can give too an Ananda which is not the highest and may on the contrary by its lure take away from the path altogether. When you have reached the stage of clear discernment where the highest Light is turned on all things that come, then experiences of many kinds may be safely faced, but now a strict vigilance must be exercised and all diversions rejected. It is necessary to keep one's steps firmly on the straight road to the Highest; all else must wait for the proper time.
A fatal Influence upon creatures stole
Whose lethal touch pursued the immortal spirit,
On life was laid the haunting finger of Death
And overcast with error, grief and pain
The soul's native will for truth and joy and light.
