yytz: there are two kinds of prayer, ritual and personal. Ritual prayer was instituted by the anshei knesses hagedola — shmona esrei brachos al haseder. Personal prayer is everything else, whether you wrote them yourself or not. I don’t daven from likutei tefillos, but I do use Yehuda Haleivi’s poems among others. But those are just my way of enhancing my personal prayer as likutei tefillos does for you. We don’t write prayers for other people and say “you should daven like this.”
