6 And blessed are all they who do hunger and thirst after righteousness, for they shall be filled with the Holy Ghost.
7 And blessed are the merciful, for they shall obtain mercy.
8 And blessed are all the pure in heart, for they shall see God.
These verses seem to be the recipe for exaltation.
Hunger + thirst for righteousness = cleansing, purifying power of the Holy Ghost
Merciful to others = mercy to us (power of Christ’s Atonement to forgive and make holy)
Purity (cleansing by Holy Ghost + mercy of Christ to forgive) = see God (exaltation)
The keys to exaltation are forgiveness, covering by Christ’s Atonement, and the fire of the Spirit to cleanse.
