Is there any risk to our student in working with and being mentored by a prominent healer?

We see little risk at this time. This is a routine function he has carried out with hundreds of individual practitioners and is just part of what he does. It is not seen as a threat to the Extraterrestrial Alliance and so this in and of itself will not create a focus on you that could lead to heightened scrutiny and a potential for greater manipulation of you personally by the darkness. So, as you have been coached by your channel, as long as you do not confront too directly the workings of the Extraterrestrial Alliance, this will not stir things up and result in a greater scrutiny of you by those who are manipulating him and keeping him under surveillance. Almost every human being you interact with is being manipulated and subjugated by the Extraterrestrial Alliance quite directly, so interacting with him poses no outsized risks at the moment compared to other people.
