What is the definitive guide to understanding Brân the Blessed in Ariel Gatoga's Welsh Mythology series?

In my Welsh Mythology work, there isn’t a single “definitive guide” volume just on Brân the Blessed; instead, I approach him through a few key lenses:

• His role in the Mabinogi (especially the Second Branch)
• His symbolism as a giant, king, and bridge between worlds
• The magical and initiatory themes around sacrifice, sovereignty, and protection

For a deep dive, I recommend combining:

• A solid translation of the Mabinogi (read the Second Branch closely)
• My lectures and discussions where I unpack his symbolism and magical applications

Are you looking for Brân primarily as a mythological study, or for practical magical work with his current?
