From WGA script / Alan Dean Fosters TFA novelization: (blocks follow each other in that order, separated by a slash)
Han discussing where Luke went:
There're a lot of rumors. Stories.
The people who knew him the best
think he went looking for the first Jedi temple.
Han turned to him. “There’ve been all kinds of rumors and stories. When people don’t have access to facts, they invent what they’d like to believe, or what they think others would like to hear. The people who knew him the best think he went on a personal quest, looking for the first Jedi temple.”
Maz Kanata: (this piece was NOT in WGA script, just the novelization)
“A map leading to the first Jedi temple!” Maz was marveling as she puttered about the kitchen. “To Skywalker himself! I’ve never given up hope for him.”
Admiral Statura discussing the map the First Order has: (this piece was NOT in WGA script, just the novelization)
Admiral Statura nodded in agreement. “It makes sense. The Empire would have been looking for the first Jedi temples. In destroying all the Jedi sanctuaries they would have acquired a great deal of peripheral information.”
Then we see Rey's vision:
She turns to look -- we PIVOT -- and see a BURNING TEMPLE AT
NIGHT. We PAN to:
Day became night, sky ominous and filled with rain, cold and chilling to the bone. She was standing, she was sitting, she was looking up—to see someone, a warrior, take the full force of the lightsaber. He screamed and fell.
Battlefield then, all around her. Putting a hand to her mouth, she rose and turned. As she turned, she found herself confronted by seven tall, cloaked figures, dark and foreboding, all armed. Soaked and shivering, she stumbled backward, turning as she half fell. Firelight illuminated her, firelight from a distant, burning temple.
