Question: Is it possible to say there are better or less successful times? For example, the destruction of the Temple is a bad time, and on the contrary, Passover, a festival about the Exodus from Egypt, is a good time?
Answer: Times like these are also on our calendar. The worst time is Tisha B’Av and the best is around the festival of Purim in the month of Adar.
Question: To what extent can a Kabbalist use the unique lights of the external calendar, i.e., the best times according to the corporeal calendar?
Answer: These times have meaning only for people who still haven’t participated in spiritual development.
And those who are already participating in it are not subject to any calendar at all. They have their own special axis of development, which is special for them from point “A” to point “B.” Therefore, for them there is no night, day, winter, summer, leap year, or regular year. For them, there are no seasons in a year. They are not subject to any calendar. Internal states are their calendar.
