The Hunt For Rakshasa | Side quests - Shangri-La Far Cry 4 Guide

You will find Thangka in a flooded cave, near a statue [X:546, Y:486]. To reach it, go to a location called Kalinga's Descent. Jump down, into the water. You can see the entrance to the cave in the screen above.

The rocks will create a safe path.

When inside, go straight, across the bridge that the rocks create. After meeting a tiger, walk along and interact with the seeker. You will receive a bow. From now, you can use it to kill enemies. The ability to slow down time will make it easier (it activates automatically as you pull the bowstring).

Don't rush into open fight - instead, eliminate the enemies from a safe distance, using your bow.

You will have the opportunity to test your new weapon very soon, in a big chamber. After going inside, don't go down right away, but eliminate the enemies standing on the scarp on the left. Then, deal with the opponents in front of you. Using the bow and with the help of the tiger, clear the area and head forward. Near the exit, you will encounter two archers - killing them requires two hits or one headshot.

Thanks to slow-motion, you have a while for aiming.

Go along the stream, heading towards the red portal. It will take you to another location. Here, try to stay unnoticed and eliminate the enemies silently. Jump down and head left to find the next portal. After going through it, use the Mani wheel and leave through the red portal.

Watch out for the archers in the temple.

Go through the temple (watch out for the archers) and go outside. Use the Auto-Cross here. You will see a lot of enemies standing on your way to the bell. Use the tiger to distract them and finish as many demons as you can from behind a cover. Watch out for the opponent that spits fire. If you're noticed, there's no point in fighting them all. Run quickly to the bell and ring it to kill the remaining enemies and complete the mission. You will be teleported to Ghale's Homestead.
