Beyond his role as a warrior, Kartikeya was also a teacher of profound wisdom. He imparted knowledge about the importance of discipline, duty, and devotion. His teachings emphasized that true strength comes from within and that wisdom and humility are the greatest virtues.
One of his famous disciples was the sage Agastya, to whom Kartikeya revealed the mysteries of the universe and the secrets of divine knowledge. These teachings became the foundation for many spiritual practices and philosophical thoughts in Hindu tradition.
