Go into the fire place and turn left you should be abel to climb the wall to a secret passage follow the passage to a room. Enter the gate then carefully make your way across the sludge. On the bookshelf on the wall on the right there is a book that you have to push.
This small lagoon has a strong current of its own, but you should be able to fight it long enough to steer into the alcove and get the Save Gem. You should spot a ledge about halfway down to the left. You should find a switch that opens the vent above the grill. One of the four relics is visible across the way, but your immediate path is pulsing with electricity. Do this twice and Lara will fly up and you have to very slowly turn around so that you are facing the red square that is there close to her roof. You could take the path to the right which is a major shortcut to the end of the level, but in doing so you would miss several secrets and ruin any chance of playing the Secret Bonus Level. Exit the Inventory screen and go back to see that you have all the items for the particular level that you're on.
Climb around and drop and grab and climb some more until you can pull up onto the ledge with the second switch. This next room is tough. Follow the hallway to a spiked ledge and kill the monkey before walking through the spikes. You will trigger a dart trap but as long as you don't move they won't hit you. Explore both areas and watch out for the snake who is waiting to attack.
Investigate the other escalator and kill anything that gets in your way. You should now be able to get the Embalming Fluid before going on. Hold walk R1 and use the D-Pad to step forward, then step back. From here you press the select button and now you can choose uzis and deserteagle and othee but these two were the only gunsyou pick. Around the corner is a ladder. Sneak past the guard and return to the red passage and use the Security Pass in the lock and climb up the ladder.
Make your way to the platform in the middle of the falls and climb the ladder. I just included it because it looked cool and it was in a jungle setting. Climb to the top of this room using the ladder and various ledges on the left. Release walk, turn around three times in either direction, back flip and roll in mid-air Down + Square, Circle.

Do not fire then run forward until after the explosion and resulting deaths. As you enter the library, turn right and find the book sticking out from the shelf.
Jump up into the secret passage and into the water. Kill the monkey then jump down so you slide onto a flat section between the spikes. Return to the trail you were on before you went after this last secret. Now you get to make your way all the way back to the Quad Bike. Sprint down the hall past the open cage and grab the Key of Ganesha. Find and push the moveable block so you can use it to climb to the ledge above.
If you returned to the start, then look under the overhang and get the ammo. Watch out for a sniper in the cathedral dome who is protecting this levels final two secretes. Note: you may need to adjust a bit when facing diagonally to the wall to get this trick work. When you get the wide angle camera view, drop and jump to do another backflip across the water. There's no going back as the door seals shut behind you. You should now be at the pit you just flooded so dive in and flip the switch to open the gate.
Once you make it to the water passage, drop down beneath the flaming ledges and pull the lever to turn off the fire. Now paddle down the green passage and put some distance between you and the hungry crocodile so you can exit the Kayak and get to shore before he bites you in half. Kill the guard up ahead then enter the crawlspace leading to the next room. They will usually not attack you, but rather make a dash for the nearest alarm switch to call in for reinforcements. Sprint down the passage as the boulder is released and rumbles toward you. Climb down the wall and shimmy to the left and pull up into the crawlspace.
Slide again and jump as the floor gives way beneath you. . If you hear a rumbling, jump or step back to avoid the rock. You can now shimmy to the left and continue, or if you want to get some extra ammo, do a daring backflip from the slope back to the block in the middle of the river and return to the start. Get all the items then climb up the ladder and backflip to the ledge. Backflip from the low area after the small gap then do one more running jump to access Secret 1.
