The Beatific Vision is the intuitive knowledge of God.

The Beatific Vision of God and the Last Days *
[From the edict “Benedictus Deus,” Jan. 29, 1336]
530 By this edict which will prevail forever, with apostolic authority we declare: that according to the common arrangement of God, souls of all the saints who departed from this world before the passion of our Lord Jesus Christ; also of the holy apostles, the martyrs, the confessors, virgins, and the other faithful who died after the holy baptism of Christ had been received by them, in whom nothing was to be purged, when they departed, nor will there be when they shall depart also in the future; or if then there was or there will be anything to be purged in these when after their death they have been purged; and the souls of children departing before the use of free will, reborn and baptized in that same baptism of Christ, when all have been baptized, immediately after their death and that aforesaid purgation in those who were in need of a purgation of this kind, even before the resumption of their bodies and the general judgment after the ascension of our Savior, our Lord Jesus Christ, into heaven, have been, are, and will be in heaven, in the kingdom of heaven and in celestial paradise with Christ, united in the company of the holy angels, and after the passion and death of our Lord Jesus Christ have seen and see the divine essence by intuitive vision, and even face to face, with no mediating creature, serving in the capacity of an object seen, but divine essence immediately revealing itself plainly, clearly, and openly, to them, and seeing thus they enjoy the same divine essence, and also that from such vision and enjoyment their souls, which now have departed, are truly blessed and they have eternal life and rest; and also [the souls] of those who afterwards will depart, will see that same divine essence, and will enjoy it before the general judgment; and that such vision of the divine essence and its enjoyment makes void the acts of faith and hope in them, inasmuch as faith and hope are proper theological virtues; and that after there has begun or will be such intuitive and face-to-face vision and enjoyment in these, the same vision and enjoyment without any interruption [intermission] or departure of the aforesaid vision and enjoyment exist continuously and will continue even up to the last judgment and from then even unto eternity.

Ecumenical XVII (Union with the Greeks, Armenians, Jacobites)
Decree for the Greeks *
[From the Bull “Laetentur coeli,” July 6, 1439]
693 De novissimis] * It has likewise defined, that, if those truly penitent have departed in the love of God, before they have made satisfaction by the worthy fruits of penance for sins of commission and omission, the souls of these are cleansed after death by purgatorial punishments; and so that they may be released from punishments of this kind, the suffrages of the living faithful are of advantage to them, namely, the sacrifices of Masses, prayers, and almsgiving, and other works of piety, which are customarily performed by the faithful for other faithful according to the institutions of the Church. And that the souls of those, who after the reception of baptism have incurred no stain of sin at all, and also those, who after the contraction of the stain of sin whether in their bodies, or when released from the same bodies, as we have said before, are purged, are immediately received into heaven, and see clearly the one and triune God Himself just as He is, yet according to the diversity of merits, one more perfectly than another. Moreover, the souls of those who depart in actual mortal sin or in original sin only, descend immediately into hell but to undergo punishments of different kinds [see n.464].
I just checked the catholic Encyclopedia and it isn’t so clear about it. Does it mean Heaven itself?
