Rosh chodesh kislev! What an oppertune time for spiritual embetterment!
"ותהי ראש החודש הזה סוף וקץ לכל צרותינו, תחילה וראש לפדיון נפשינו"- We see a lot of times dates in Judaism are meant to be an inspiration for action. But it's not that the date itself intrinsically has the power to change how we were acting untill then, but that it should inspire us to insightful and logical thoughts that do have the power to inspire us to 'change our evil ways', and maybe even perhaps keep those resoulutions we made on Yom Kippur.
On Rosh chodesh, more than normally, when saying yaaleh v'yavo, and saying "!והושיענו בו לחיים" that thoughts of strategies about how to have more restraint in action, and resist instinctive action once and for all should traverse a persons mind. How could we ask G-d for 'good life' this month, and ask him for this month to be the end of all our evils if we're not being very active in how to curb our desires? "!הבא לטהר מסעיין לו"- Only someone who's proactive about it will receive help from g-d! But then help he will defenetely receive.
Why is it that so long, and through so many situations we can't mannage to understand ourselves (or, in the words of 'sefer cheshbon hanefesh'- "our elephant"), and finally take full controll of ourselves and our lives? We have tryed many statagies? The truth is we have done it in the past, and we know we can do it again, all we need is a lot more active effort! Everything depends on it!
