When I tied a pair of tzitzit, I tied a double knot to the garment and for the final knot, but for the three knots in between the chulyot (subsections of string wrappings), I tied single knots. Is that sufficient?
When I eat a fruit and drink, if I finish the fruit but will continue drinking for quite a while, when should I recite Borei Nefashot? If I do it after finishing the fruit, should I make a new beracha on the drink?
We obviously can't understand how God runs the world. On the other hand, the questions, ramifications, and thoughts that inevitably arise out of our Godly intelligence and curiosity, in such an extreme and rare world crisis, are surely part (!) of what is meant to preoccupy us. Rather than seeing this as a "punishment" of an angry god, which is more fitting for a childish or pagan world-view, we believe that our loving Father works through sending us "educational lessons" or challenges, which build us and help us notice problems or shortcomings in our current routine. These 20+ social, familial, religious, universal, national, and Zionist outcomes, are surely meant to be noticed, to reap the benefits of "Gam zu l'tova!", "all God does is for the best!"
When after fastening the tefillin shel yad, I find part of my sleeve under the tefillin and pull it away, must I refasten the tefillin due to the rule of ta’aseh v’lo min ha’asuy (=tvlmh – mitzva-related actions must be performed directly)? In this case, the placement of the tefillin becomes proper not by fastening them but by removing something else!
