“The three kingdoms of widely differing glories are organized on an orderly plan of gradation. We have seen that the telestial kingdom comprises several subdivisions; this also is the case, we are told, with the celestial; (D&C 131:1, 2 Cor 12:1-4) and, by analogy, we conclude that a similar condition prevails in the terrestrial. Thus the innumerable degrees of merit amongst mankind are provided for in an infinity of graded glories. The celestial kingdom is supremely honored by the personal ministrations of the Father and the Son. The terrestrial kingdom will be administered through the higher, without a fulness of glory. The telestial is governed through the ministrations of the terrestrial, by “angels who are appointed to minister for them.” (D&C 76:86-88)

Glory of the stars] Telestial glory found only in the telestial kingdom. “In the infinite mercy of a beneficent Father it [telestial kingdom] surpasses all mortal understanding, and yet it is in no way comparable to the glory of the terrestrial and celestial worlds. Telestial glory is typified by the stars of the firmament, and ‘as one star differs from another star in glory, even so differs one from another in glory in the telestial world’ (D. & C. 76:81-112; 1 Cor. 15:41), meaning that all who inherit the telestial kingdom will not receive the same glory.” (Mormon Doctrine, 2nd ed., p. 778.)
