"Bless the Lord, O my soul... who walketh upon the wings of the wind." (Psalm 104:1a, 3b) "The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit." (John 3:8)
The same word in Greek for "Spirit" is that for wind: pneuma. The Holy Spirit is indeed that breath of invisible, gentle (hopefully) and mysterious force. But I find the biggest misconception is that which I just alluded to. The Holy Spirit, while I'm hesitant to call it good by labeling...The Holy Spirit, under a male pronoun, I can't rest not seeing Him for who He is. And that is, not an inanimate "force". The Holy Spirit is so much more than we can comprehend. Because of what Jesus did in shedding His blood for sinful humanity, The Holy Spirit, has been loosed on the world at large. And as a child of God, you have exclusive access to Him whereas anyone else must first see Jesus. And then be introduced to the Holy Spirit who was there all along.
"Then said Jesus to them again, Peace be unto you: as my Father hath sent me, even so send I you. And when He had said this, He breathed on them, and saith unto them, Receive ye the Holy Ghost:" (John 20:21-22)
To insufflate means to breath in or upon. It changes definition slightly be it in an Ecclesiastical or Medical setting. But not by much. The Holy Spirit as the breath of God has been breathed out by the Lord Jesus and what else is He doing? He's here to flow in and out and among the Body of Christ and to get us ready as His bride. "The Spirit and the bride say Come." (Revelation 22:17)
If you've ever heard the Holy Spirit speak to you, you know that He has a voice distinct from the Father and of the Son. He is just as much God as they and He will only witness to what they want done. While much has been written on the Holy Spirit, I feel that a lot of what we are supposed to do in learning how to move in concert with Him comes, not so much by trial and error (there is that), but by filling our hearts and minds with the Word of God--what it does say about Him, and then letting Him reveal Himself to us through our ordinary day-to-day activities.
"Howbeit when He, the Spirit of truth, is come, He will guide you into all truth: for He shall not speak of Himself; but whatsoever He shall hear, that shall he speak: and He will show you things to come. He shall glorify me: for He shall receive of mine, and shall shew it unto you." (John 16:13-14)
I have not wrapped my mind around the Holy Spirit. I do know that He is the substrate that we live upon. I don't mean to sound fanatical but because of what Jesus did, there is a foundation of love, joy, peace (really, all the fruits of the Spirit--see Galatians 5:22-23) beneath our feet (figuratively) that, as we walk in Him (see Galatians 5:16), we will always be a part of (there is nothing below Him). This is what Jesus meant when He came to deliver Him to us. Have I "grieve[d]" Him (Ephesians 4:30)? Sure I have. And I'm most certainly not proud. Have I "quench[ed]" Him (1 Thessalonians 5:19)? Absolutely. And I am seeking as the days, weeks, months go by, to attune myself more in line with His impulses and thoughts and answers. But it's a process. Not every single answer for each specific instance is to be found in the pages of the Bible. But as I go on in fellowship with Him, following Jesus to the best of my ability, I find that the Holy Spirit is more present than I know. And more loving, kind, and patient than I ever deserve.
"If we live in the Spirit, let us also walk in the Spirit." (Galatians 5:25)
