The different forms of showing respect are :
* Pratuthana – rising to welcome a person.
* Namaskaara – paying homage in the form of namaste .
* Upasangrahan – touching the feet of elders or teachers.
* Shaastaanga – prostrating fully with the feet, knees, stomach, chest, forehead and arms touching the ground in front of elders.
* Pratyabivaadana – returning a greeting.
Rules are prescribed in our scriptures as to who should prostrate to whom. Wealth, family name, age, moral strength and spiritual knowledge in ascending order of importance qualified men to receive respect. This is why a king though the ruler of the land, would prostrate before a spiritual master. Epics like the Ramayana and Mahabharata have many stories highlighting this aspect.
This tradition thus creates an environment of mutual love and respect among people ensuring harmony in the family and society.
