I think, it is also important that we have some conceptual understanding on what third eye is. Here is an explanation from Jaime Licauco:

(I used to listen Jimmy Licauco before in his DZMM program, Inner Mind on Radio. He is also writing columns in Inquirer. I pick this because he explain it with scientific bases.)
He explained that everyone can develop his third eye. He dismisses the common belief that third eye can be developed using oracion or the like.
This explains that third eye is a natural gift that can be developed. This is not a curse.
