Upadhyaya

1. An Acharya is an ordinary instructor. 
2. He is called an Upadhyaya who teaches the Vedas. The Upadhyaya is greater than even ten Acharyas or ordinary teachers. 
3. The father, again, deserves ten times as much respect as is paid to the Upadhyaya. 
4. As regards the mother, again, the reverence due to her is greater than what is due to the father. The mother is equal to the whole earth.
