Why Would Pope Francis Tell The World About His Own Private Revelation Of Being Filled With The Great Light On Election Night?

And no wonder: for Satan himself transformeth himself into an angel of light. ii.Cor.xi.xiv.
On the Pope's private revelation he had on the night of his election. Why did the Pope reveal this very private revelation for all the world to admire?
At one point in the text, Scalfari raises the question of mysticism with Pope Francis, and asks if he’s had mystical experiences.

Here is the reply as presented by Scalfari, in the English translation La Repubblica published of the interview:

“Rarely. For example, when the conclave elected me Pope. Before I accepted I asked if I could spend a few minutes in the room next to the one with the balcony overlooking the square. My head was completely empty and I was seized by a great anxiety. To make it go way and relax I closed my eyes and made every thought disappear, even the thought of refusing to accept the position, as the liturgical procedure allows. I closed my eyes and I no longer had any anxiety or emotion. At a certain point I was filled with a great light. It lasted a moment, but to me it seemed very long. Then the light faded, I got up suddenly and walked into the room where the cardinals were waiting and the table on which was the act of acceptance. I signed it, the Cardinal Camerlengo countersigned it and then on the balcony there was the ‘Habemus Papam’.” NCR Read More>>>
In September, the Pope warns the world about private revelations:
There’s another kind of Christian without Christ, he continued, “those who seek things that are a little uncommon, a little special, that go back to private revelations,” while the Revelation concluded with the New Testament. Pope Francis warned about the desire of these Christians to go to “a spectacle of revelation, to hear new things.” But, the Pope exhorted them, “take the Gospel!”
But in October the Pope tells the world:
At a certain point I was filled with a great light. It lasted a moment, but to me it seemed very long. Then the light faded, I got up
I'm sorry but doesn't the "great light" qualify as a "private" revelation? So why does the Pope condemn others for what he himself engages in? And why oh why tell any one about this "great light".

Are there no dangers in telling the world about ones mystical experiences? Is the pope looking to be admired as a Mystic? Here read from Tanquerey:
1511. e) When a spiritual director is told by a penitent of his supposed revelations, he should carefully refrain from  showing any admiration, for this would lead the seer at once to consider these visions as true, and perhaps to take pride in them. He must rather explain that such things are of far less importance than the practice of virtue, that  one can easily be deceived in these matters and that one must therefore suspect, and at the beginning discount, such visions, rather than take stock in them.

This is the rule laid down by the Saints. St. Teresa " says : " Some times, and often, it may be only fancy, especially if the persons have a weak imagination, or are subject to great melancholy. No attention is, in my opinion, to be paid to these two kinds of persons... Such things are always to be feared until the spirit is understood. I consider it best to resist these " discourses " at first, because if they come from God they are a great help to advance us onwards ; they also increase when they are thus tried. This is the case ; but the soul should not be troubled too much, for truly she cannot do -otherwise ". St. John of  the Cross is still more emphatic, pointing out the six main drawbacks of a too ready acceptance of such visions, he adds : " The devil rejoices greatly when a soul seeks after revelations and is ready to accept them; for such conduct furnishes him with many opportunities of insinuating delusions, and derogating from faith as much as he possibly can ; for such a soul becomes rough and rude, and falls frequently into many temptations and unseemly habits. "
Who told the Pope that his "great light" was legit?

Telling the whole world about his private revelation is a little creepy to say the least. There's no humility in telling the world about ones private revelations.

This Pope is a disaster.

Pay Attention!

“In the year 1864, Lucifer together with a large number of demons will be unloosed from hell; they will put an end to faith little by little, even in those dedicated to God. They will blind them in such a way, that, unless they are blessed with a special grace, these people will take on the spirit of these angels of hell; several religious institutions will lose all faith and will lose many souls.Our Lady of La Salette 19 Sept. 1846 (Published by Mélanie 1879) 
Several will abandon the faith, and a great number of priests and members of religious orders will break away from the true religion; among these people there will even be bishops. Our Lady of La Salette 19 Sept. 1846 (Published by Mélanie 1879)
