What are the core principles of Ariel Gatoga's Druid Triad in witchcraft?

The Druid Triad names three spiritual instructors of humankind that form a path of training in witchcraft and magic:

• Mastery of self – training the mind, emotions, and desires. This includes discipline, self-observation, purification of thought, and cultivating inner peace and clarity.
• Mastery of world – learning to work skillfully with outer conditions: resources, timing, relationships, and the forces of nature and the elements.
• Mastery of the unknown – developing a conscious, respectful relationship with the unseen: intuition, subtle forces, spirits, and mystery itself.

Together they describe a holistic path: first stabilizing the inner self, then harmonizing with the outer world, and finally approaching the mysteries beyond ordinary understanding.
