The thing is, your higher self is the "real" you and the part of you that is wondering about it, is the "unreal" you... and it does not truly matter what the unreal part of you feels. So there is no wrong way to speak to your Higher Self.
I would suggest giving yourself permission to imagine that you actually have a Higher Self. And then sitting quietly in a pleasant place, and calming yourself... looking at the world around you... noticing your senses... noticing your emotions...noticing all the thoughts which float by... but all with the underlying feeling that what is deeply truly you... is the One watching, not the things watched. Not even the ideas, emotions, sensations. They serve you, they are not you. This is sometimes called mindful meditation.
Then your "watching self" can say "yeah, I give myself permission to ask my Higher Self, whatever that is, to attune me to such-and-such a system. And let yourself receive the attunement, whether you feel anything or not. Remember the energy sensations people talk about, are not their "true" selves... just sensations.
