You are confused again. What I stated is;
.. there are SEVERAL definitions for "spirit". It depends on the context. Most of the times, in Scripture "spirit" is discussing thinking, attitude. Some times "spirit" means breath. Some times spirit means a being with a message, a messenger.
Jesus' spirit is conformed to his God's spirit.The holy spirit is God's spirit. God's thinking/mind and the power produced by God's mind. So, yes they think the same. The believer then must "learn" what Christ taught, in order to acquire Christ's spirit, which has been perfectly conformed to his God's spirit.
Eph 4:17-24
17 So this I say, and affirm together with the Lord, that you walk no longer just as the Gentiles also walk, in the futility of their mind,
18 being darkened in their understanding, excluded from the life of God because of the ignorance that is in them, because of the hardness of their heart;
19 and they, having become callous, have given themselves over to sensuality for the practice of every kind of impurity with greediness.
20 But you did not learn Christ in this way,
21 if indeed you have heard him and have been taught in him, just as truth is in Jesus,
22 that, in reference to your former manner of life, you lay aside the old self, which is being corrupted in accordance with the lusts of deceit,
23 and that you be renewed in the spirit of your mind,
24 and put on the new self, which in the likeness of God has been created in righteousness and holiness of the truth.
