These are the contexts of the quotes tweeted from @sueannbowling between December 12 and December 18, 2013. All but the last are from The Fellowship of the Ring, by J.R.R. Tolkien.
“I do not council you one way or the other.” Galadriel, offering Frodo a look in her mirror.
“Seeing is both good and perilous.” Galadriel. Continues, “Yet I think, Frodo, that you have courage and wisdom enough for the venture, or I would not have brought you here.”
“And what do you wish?” “That what should be shall be”. Galadriel has just told Frodo that if he succeeds in destroying the ring, all that has been wrought with the three Elven-Rings (including the one she wears) will end. He questions her, and she answers.
“All shall love me and despair!” Part of Galadriel’s understanding of what would happen if she were to claim the ring.
“That is how it would begin. But it would not stop with that, alas.” Still Galadriel, recognizing that power leads to the desire for power for its own sake, no matter how selfless the initial reason for taking it.
“What ship would bear me ever back across so wide a sea?” The end of Galadriel’s song as she joins the fellowship for farewell.
“As a player himself, he had no use for unruly fans.” Bowling, Tourist Trap. Xazhar is talking to the planetary administrator, who is considering having him represent her at the Plasmaball tournament.
