Standing and walking meditation

When you noticed that i'm not looking or greeting at anyone of you. Please do not feel that I'm proud bc I might be doing walking meditation. What is it? It means that I am reciting mantra while walking. At this period,I must not talk to anyone,if not i will fail in it. A successful walking meditation is when you really cannot feel anyone or even yourself at where about. You have to remain your brain as pure and empty as possible. It is somehow difficult. =DDD
