Dingnamaskara--
Late in my studies,my guru Sri Krishnamacharya taught me a charming routine called Dik (ding) namaskara or salutations to the directions.
Ding namaskara (dik+ namaskara) actually is part of the daily routine in India among those who do sandhyavandana (prachyai dise namah...). For more on sandhyavandana see my article in namarupa magazine. Ding nmaskara in our daily is abridged mantras and vinyasas. Sri Krishnamacharya used the full mantras and vinyasas. These mantras are actually from the svadhyaya chapter of the Yajurveda.

One view is that in the olden days when spiritual discussions by scholars and sages took place in the Gangetic plain, many laymen and even the celestial beings travelled long distances through difficult terrain over a long time usually by walk to attend the gathering. So the first thing they would do is to pay respects to the divine beings (gods)guarding the direction, east, south, west, north, the upward direction, the downward and the intermediate directions, and also thanking the guarding angels for giving them safe passage. This ding namaskara became a part of the daily routine.
