Voice of the soul

I can touch you,

But you can't touch me,

I can understand you,

So you can feel me,

And I'm the one,

If you want my help,

I'm always with you,

When getting bored,

I depart from you,

But I'm always with you.

I have lots of masks,

But only one will suit you well,

So stay calm with me,

Then you can understand me,

I'm the voice of the soul,

But there is one question for you,

Who am I?
