Check out the internet with the many other meanings.
Notes: for the meaning in the above website I would like to point there are no words in the sloka for a teacher or student or lord or to be protected. One website writes ma visha, to mean let us never be poisoned, it is ma vid visha so knowing that it would not make sense to think of it that way. Nonetheless, the meanings from the all of the other websites though there are variations convey the over all meaning if that is all you care about. Since I am particular about what makes sense to me and how I understand things that is reading from left to right, and taking a deeper look at the meaning to understand it and making sense of it in way it is meant to be understood in Sanskrit I am happy with my interpretation.
