I think I just found most realistic explanation of "palden" without any abbreviations. Remember that we discussed the interchangeability of "p" and "b" in the beginning of MHD words. So considering "palden", one should look also for "balden" (as Helmut also considers above)!
Here's what the MHD dictionary (You are not allowed to view links. Register or Login to view.) gives for "balden":
1) "kühn werden, erstarken, erdreisten"
2) "schnell werden, eilen", notably "hin bald von mir, Sathanas!"
So it's either "to strenghten" or "to dare", or "to hurry up" (the latter relevant in meaning to "soon" which Helmut outlined above).
