The holy spirit is the one who teaches us to discern the meaning of the spiritual experiences we're having .
He teaches you the meaning of the fire you felt burning in your palm .
He teaches you the meaning of the fire you felt burning within your heart .
He teaches you the meaning of the oily or fiery sensation you feel on your tongue .
And all other types of sensations or feelings you might be having .

Take your time and
Read these verses carefully to the end

1 Corinthians 2:9-15
[9]But, on the contrary, as the Scripture says, What eye has not seen and ear has not heard and has not entered into the heart of man, [all that] God has prepared (made and keeps ready) for those who love Him [who hold Him in affectionate reverence, promptly obeying Him and gratefully recognizing the benefits He has bestowed]. [Isa. 64:4; 65:17.]

[10]Yet to us God has unveiled and revealed them by and through His Spirit, for the [Holy] Spirit searches diligently, exploring and examining everything, even sounding the profound and bottomless things of God [the divine counsels and things hidden and beyond man's scrutiny].

[11]For what person perceives (knows and understands) what passes through a man's thoughts except the man's own spirit within him? Just so no one discerns (comes to know and comprehend) the thoughts of God except the Spirit of God.
[12]Now we have not received the spirit [that belongs to] the world, but the [Holy] Spirit Who is from God, [given to us] that we might realize and comprehend and appreciate the gifts [of divine favor and blessing so freely and lavishly] bestowed on us by God.

[13]And we are setting these truths forth in words not taught by human wisdom but taught by the [Holy] Spirit, combining and interpreting spiritual truths with spiritual language [to those who possess the Holy Spirit].

[14]But the natural, nonspiritual man does not accept or welcome or admit into his heart the gifts and teachings and revelations of the Spirit of God, for they are folly (meaningless nonsense) to him; and he is incapable of knowing them [of progressively recognizing, understanding, and becoming better acquainted with them] because they are spiritually discerned and estimated and appreciated.

[15]But the spiritual man tries all things [he examines, investigates, inquires into, questions, and discerns all things], yet is himself to be put on trial and judged by no one [he can read the meaning of everything, but no one can properly discern or appraise or get an insight into him].

What does it mean when your hands shakes while you pray ?

Someone might be thinking or doing bout this

Why does it mean when you felt fiery sensation on a part of your body ?

Any person might be wondering

No one knows the things of a man except the man's spirit .
now
The spirit of a man is the lamp of the lord searching all the inner depth of his heart .

Mark 2:8
[8]But immediately, when Jesus perceived in His spirit that they reasoned thus within themselves, He said to them, “Why do you reason about these things in your hearts?

The way to perceive (which also men's RECEIVE ) is to connect your mind with the holy ghost ,and stay in the mindfulness of him
