What is Holy?

I feel sometimes I miss the meanings of words. Or I know them but I miss the fullness of them. If I don't take the fullness of the word then I guess I'm not really defining it. So what does that matter well I was contemplating Holy.
What is holy?

I've been asking God what holy looks like. Because as I explore that he is holy God, it seems he is characterized that not only in the purity realm but also in the way he loves me, in the way he creates things, holy in the way that he exists, holy in every attribute.

So the idea that holy is adverb. It's more than an adjective describing one realm. If it is, then how do I respond to people likewise?
If with holiness I were to love someone then I would therefore love them beyond myself, and there it would be completely selfless

If with holiness I act, then I would then consider my actions not by my own interest, but rather by need of someone else

If with holiness I enter whatever I do, then I step aside I am no longer responding to my desires but I'm existing like my father.

If holiness in how I see myself, then I no longer see circumstances I begin see life as opportunity, secondly I no longer compare myself for lacking or in pride, rather I solely compare myself with Jesus.

Just a thought. I think I could read this everyday and never have attained this, but I pray I can to some degree a little more everyday.
