Yoda says to Kanan "I am here because you are here". Qui-Gon Jinn said the same thing to Obi-Wan Kenobi in the Clone Wars episode Overlords (2011).
The designs that adorn the Jedi temple walls as well as some of the structure are based on paintings developed by concept artist Ralph McQuarrie for the temple on Yavin IV in the 1995 book "The Illustrated Star Wars Universe".
The working title for "Path of the Jedi" was "Enlightenment".
An earlier version of the script featured a subplot in which Old Djo and Cikatro Vizago teamed up to steal the Kyber crystal from Ezra and Kanan.
How the Grand Inquisitor defeated Kanan in the vision is reminiscent of the Clone Wars micro series where Grievous unleashed his two extra arms and lightsabers to overwhelm and defeat the Jedi in his way.
