The next temple ordinances to talk of are what members generally refer to as "Initiatories." And the best explanation I would be the following (originally found here):
I very much love the initiatory ordinances. I love symbolism, and these ordinances have that. But I especially love the blessings promised. I loved to hear them the first few years I was able to perform these ordinances for the dead. But 8 years ago, I had the very wonderful blessing of being called as a temple ordinance worker. As such, I helped to administer these ordinances among the female temple patrons who were doing work either for themselves or for the dead. I memorized the words to all the initiatory ordinances (among other ordinances) and then knew the words better than I had before. Those promised blessings became embedded in my mind, my heart, and my soul. Because of this, those ordinances are more able to give me unspeakable comfort, hope, and direction.
