I have never heard of it, googled it now and seems like it is some sort of new age "spirit guide". New Age is similar shit program as other religions, it is all about "love" (self-sacrifice) and suffering just like xianity. Years ago I read a new age book by Chelsea Quinn Yarbro that was supposedly channeled by some "Michael" being. The being explained bullshit about how life is a spiritual game that ends in all people becoming one... This Alaje is possibly similar, I'm not going to open any videos or web-pages of this but from what I saw by reading site and video names "love meditation from pleidian Alaje" etc I can certainly state this is new age rubbish.

This is fake new age spirituality that is the same as xianity, the people who claim to contact these entities actually do so with the grays or the jewish mental forms.
