Jesus on "spiritual direction" . . .

"Do not let your hearts be troubled. Trust in God[a]; trust also in me.

I am the way and the truth and the life. No one comes to the Father except through me.

Believe me when I say that I am in the Father and the Father is in me

I will ask the Father, and he will give you another Counselor to be with you forever— 17the Spirit of truth.

All this I have spoken while still with you. 26But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.

If you remain in me and my words remain in you, ask whatever you wish, and it will be given you. 8This is to my Father's glory, that you bear much fruit, showing yourselves to be my disciples.
9"As the Father has loved me, so have I loved you. Now remain in my love. 10If you obey my commands, you will remain in my love, just as I have obeyed my Father's commands and remain in his love.
When the Counselor comes, whom I will send to you from the Father, the Spirit of truth who goes out from the Father, he will testify about me.

I have much more to say to you, more than you can now bear. 13But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come. 14He will bring glory to me by taking from what is mine and making it known to you. 15All that belongs to the Father is mine. That is why I said the Spirit will take from what is mine and make it known to you.

I have told you these things, so that in me you may have peace. In this world you will have trouble. But take heart! I have overcome the world."

My prayer is not that you take them out of the world but that you protect them from the evil one. 16They are not of the world, even as I am not of it. 17Sanctify[b] them by the truth; your word is truth. 18As you sent me into the world, I have sent them into the world. 19For them I sanctify myself, that they too may be truly sanctified.

My prayer is not for them alone. I pray also for those who will believe in me through their message, 21that all of them may be one, Father, just as you are in me and I am in you

I have made you known to them, and will continue to make you known in order that the love you have for me may be in them and that I myself may be in them."

what the Apostle John has to say on the subject:
1 John 2:20-27 (New International Version)

20But you have an anointing from the Holy One, and all of you know the truth.[a] 21I do not write to you because you do not know the truth, but because you do know it and because no lie comes from the truth. 22Who is the liar? It is the man who denies that Jesus is the Christ. Such a man is the antichrist—he denies the Father and the Son. 23No one who denies the Son has the Father; whoever acknowledges the Son has the Father also.

24See that what you have heard from the beginning remains in you. If it does, you also will remain in the Son and in the Father. 25And this is what he promised us—even eternal life.

26I am writing these things to you about those who are trying to lead you astray. 27As for you, the anointing you received from him remains in you, and you do not need anyone to teach you. But as his anointing teaches you about all things and as that anointing is real, not counterfeit—just as it has taught you, remain in him.

and one more from the Apostle Paul:
1 Corinthians 2:6-16 (New International Version)

Wisdom From the Spirit
6We do, however, speak a message of wisdom among the mature, but not the wisdom of this age or of the rulers of this age, who are coming to nothing. 7No, we speak of God's secret wisdom, a wisdom that has been hidden and that God destined for our glory before time began. 8None of the rulers of this age understood it, for if they had, they would not have crucified the Lord of glory. 9However, as it is written:
"No eye has seen,
no ear has heard,
no mind has conceived
what God has prepared for those who love him"[a]— 10but God has revealed it to us by his Spirit.
The Spirit searches all things, even the deep things of God. 11For who among men knows the thoughts of a man except the man's spirit within him? In the same way no one knows the thoughts of God except the Spirit of God. 12We have not received the spirit of the world but the Spirit who is from God, that we may understand what God has freely given us. 13This is what we speak, not in words taught us by human wisdom but in words taught by the Spirit, expressing spiritual truths in spiritual words.[b] 14The man without the Spirit does not accept the things that come from the Spirit of God, for they are foolishness to him, and he cannot understand them, because they are spiritually discerned. 15The spiritual man makes judgments about all things, but he himself is not subject to any man's judgment:
16"For who has known the mind of the Lord
that he may instruct him?"[c] But we have the mind of Christ.
