I remember a conversation with my father when I was 5 years old.
Although he was my primary Guru, he asked me to learn from his contemporaries and other teachers. I wanted to know the reason for this. His response was that we learn continuously only through the 4 dimensions prescribed in the Vedas. I could not comprehend or appreciate what he was saying at that age.
After my learning sessions with other teachers, my father would ask me to reflect on the teachings to ensure I understood the concepts well.
Today when I sit back and reflect, I realise all the continuous learning in my life was possible because it was based on the 4 dimensions as advised by my father.
