There are someone in my mind.

[Catapult]

Hello,

There are someone talking in my mind advising me something.
That someone advice me good things, I do not know.

Well, I am afraid to be tricked.
How do I know if that someone came from God, or it is the Holy Spirit?

One more is that I am very obsessed with something, it is a not a thing; however an imagination planned to be a thing.
I can't resist in that obsession.
That something is my inspiration in everything.
If I would do something, like a project or works, I always think of this something.

I am now afraid that I may or I am violating already the law of God; the idolatry.
It also remind me of verse of Luke 12:33, "Sell your possessions and give to the poor. Provide purses for yourselves that will not wear out, a treasure in heaven that will never fail, where no thief comes near and no moth destroys."

If for example I sell my favorite thing, to which I am obsessed to, and give the money to the poor would that be good?

Look again," Provide purses for yourselves that will not wear out, a treasure in heaven that will never fail, where no thief comes near and no moth destroys".

How can I provide purse? What kind of thing is in that purse?

God bless.

I'm really confused by the bulk of your post, as you seem to try to being purposefully vague, and therefore making it difficult to know what you mean. But the end part about 'treasure in heaven' simply means not to make material possessions whats important to you. But let your hearts desires be in the rewards of heaven, earned through your good works, led by the Holy Spirit. Focusing on money, cars, big houses, etc is a distraction from our walk, and all that stuff will eventually disappear and all the hard work we put in to getting these things will be useless in the end.
To enter into idolatry means to make a person, thing, idea, or whatever else a higher priority than God. If God were to tell you to, i don't know, lets say throw out all your secular music (don't know if you have any, but not the point) and you decide keeping your music is more important than obeying God, then that would be an example of idolatry.
