I am not going to give Padanamaskar to anybody because you and I are one. Easwara Sarva Bhutanam (God is the in dweller of all beings). The same Atma is present in you, me and everybody. So, there is no need for anyone to do Namaskar to anybody for that matter. You may do Namaskar to your parents so far as you and they do not realise this truth. Since I know the thuth, I shall follow it. If you still want to do namaskar, do it mentally. Join the palms to bring your ten fingers together and pray: "Swami, I offer my ten senses to you." that is enough. you don't need to touch my feet to do Namaskar
