It was cowardly in its fervor. I dont think it is  the first time I do such prayers a bit crookedly. The fact is, it is ok to ask once but I spent the whole walk reciting mantra to that purpose. It was almost a frivolous prayer in that sense. I certainly was not terrified that much about it and it is not like my life was in danger! Anyway, god was grand and when he saw my real fervor when I fell, my fervour in green Tara, he let me get back up and walk for the rest of the afternoon. Watch out afterwards though: ouchy.
