The inner and outer tents

I have to leave Hebrews 9 because I do not quite get passed 9:8-9a.
By this the Holy Spirit indicates that the way into the sanctuary is not yet opened as long as the outer tent is still standing
(which is symbolic for the present age) (Hebrews 9:8-9a).
The outer tent was where the priests offered daily sacrifices . The inner tent, the sanctuary, the Holy of the Holies, was where the High Priest entered, once a year on the Day of Atonement, to offer sacrifices to cleanse the altar and the sins of himself and of the people. Why was it that the Holy of the Holies was not yet opened? The outer tent is symbolic of the present age. What does it mean?
Today, the Catholic Church celebrates the feast of St. Francis de Sales (1567-1622). In reading his life, I was impressed by his patience. He worked patiently.
"... Throughout his life, he waited for God's will to be clear. He never wanted to push his will on God ..."
I think St. Francis is a good model for me. Ragging my brain in search of God's will, I feel like a deaf and blind man. Perhaps I should switch to other sense organs, use my heart to love Him more. Once, he said,
"... those who love God can never stop thinking about him, longing for him, aspiring to him, and speaking about him. If they could, they would engrave the name of Jesus on the hearts of all humankind."
St. Francis de Sales, pray for me. Amen.

Dear Lord, You have entered the Heavenly sanctuary to redeem our sins. How do we repay You for such grace? My heart is still smothered with arrogance, desires and worries. I am not a good farmer. Rectify my heart, I beg You. Amen.

P.S.
The author of Hebrews was telling the readers that the Old Covenant, whose zenith was the Temple cult which was supposed to repair any damaged relation between God and man, was only a faint copy of the real Covenant yet to come. People were yearning for holiness, for maintaining a good relationship with God and to attain holiness. Yet, sacrifices have to be offered daily and yearly. Moreover, the access to holiness was limited to the High Priest and only once a year. That probably was what the author of Hebrews meant when he said the true heavenly sanctuary was not opened as long as the Old Covenant, the old system was still standing. People were preoccupied with too many outward activities which were ineffective. Their conscience failed to gain any peace after all these hustles.
According to this arrangement, gifts and sacrifices are offered which cannot perfect the conscience of the worshiper (Hebrews 9:9b)
The fact that this Temple service was carried out daily and yearly suggests that this Old Covenant was ineffective. Not only God, but also man had grown impatient with this temporary arrangement. It must be replaced by a more nearly perfect one. Here comes the opportunity.
But when Christ appeared as a high priest of the good things that have come, then through the greater and more perfect tent (not made with hands, that is, not of this creation)
he entered once for all into the Holy Place, taking not the blood of goats and calves but his own blood, thus securing an eternal redemption (Hebrews 9:11-12).
Jesus is the perfect High Priest. He doesn't need to sacrifice repeatedly. While the earthly high priests needed the blood of bulls and goats for the atonement, Jesus was making use of his own precious blood to secure our redemption. Moreover, he is now sitting at the right hand of God. He has successfully entered the true sanctuary. He  has opened the once closed sanctuary for us. Now, we can attain perfection.
The author then gives a very interesting reason why Jesus must die. He took the New Covenant established by Jesus to be a will. He argues that a will will take effect only after the death of the one making the will. So, Jesus must die in order to establish the New Covenant.
For where a will is involved, the death of the one who made it must be established.
For a will takes effect only at death, since it is not in force as long as the one who made it is alive (Hebrews 9:16-17).
Even the previous Covenant was sealed with blood.
saying, "This is the blood of the covenant which God commanded you." (Hebrews 9:20, Exodus 24:8)
Then the author imperceptibly introduces another element into Jesus' death. Like the earthly sacrifices, Jesus' blood effects the cleansing of sins.
Indeed, under the law almost everything is purified with blood, and without the shedding of blood there is no forgiveness of sins (Hebrews 9:22).

Yes, almost everything. Almost! Which means there are situations in which water is enough to purify.
But as it is, he has appeared once for all at the end of the age to put away sin by the sacrifice of himself (Hebrews 9:26b).

Appendix:
This is the blood of the covenant which God commanded you.
τοῦτο τὸ αἷμα τῆς διαθήκης ἧς ἐνετείλατο πρὸς ὑμᾶς ὁ θεός. (Hebrews 9:20)
Behold the blood of the covenant which the LORD has made with you in accordance with all these words.Ἰδοὺ τὸ αἷμα τῆς διαθήκης, ἧς διέθετο κύριος πρὸς ὑμᾶς περὶ πάντων τῶν λόγων τούτων. (Exodus 24:8b)
