To obtain Teachings of Transience, you need to complete the Violet Court, a Domain of Mastery located in Inazuma. The Violet Court is located on an island directly west of Inazuma City.
Normally, you need to unlock the Wave Rider waypoint on Amakane Island to summon a Skiff, but you can swim to the domain if your stamina is high enough.
To enter Violet Court I, you need to be Adventure Rank 27. It is recommended to have your party about Level 38 and characters that use Electro.
Check the image below for the exact location.
Violet Court rotates the rewards you get based on what day of the week it is.
On Mondays and Thursdays, the domain is called Reign of Violet, and you can get the Transience Talent Level-up Materials.
On Sunday, you can choose whatever domain you desire.
Teachings of Transience are rewarded for completing Domain of Mastery: Reign of Violet I, and you can receive between one to three of them per run.
If you have completed the domain successfully, to claim the rewards, you need to spend 20 Original Resin or use a Condensed Resin to receive double. You do not have to claim the rewards if you choose not to do so.
