Only Simcha will Bring Moshiach!

There is no explanation why Moshiach hasn't come: it is certain that every Jew has done tshuva; the Tehillim of Dovid Malka Meshicha have been recited in the greatest quantity; many farbrengens have been held; the spreading of the wellsprings [of Chassidus] has been going on since the Baal Shem Tov, more than seven generations[...]

If so, the question is asked: what more can be done that hasn't already been done?!...
We could say that the thing which still wasn't done in order to bring Moshiach is -- the desired service of simcha [joy] in order to bring Moshiach.

In addition to the fact that "simcha breaks all limitations", including the limitations of golus [exile], there is a special segulah [hidden power] in simcha to bring the geulah -- as explained that Hashem's simcha atzmis [true, essential joy] will come with the building of the 3rd Bais Hamikdash, and we awaken this simcha atzmis through simcha shel mitzva, that the simcha shel mitzvah reaches higher than the mitzvah itself, and through it davka we awaken the simcha atzmis of the Time to Come.

Even though there was certainly simcha shel mitzvah in all the previous generations, since simcha shel mitzvah is a fundemental matter in serving Hashem, as it is written "serve Hashem with simcha", and "you served Hashem your G-d with simcha and goodness of heart"...nonetheless, in any case, in simcha shel mitzvah the main emphasis on the way of doing the service, that the service needs to be with simcha, and if we are speaking here about the simcha to bring Moshiach it is -- on the simcha itself simcha b'taharasa [pure simcha], the service of simcha for the sake of the goal and tachlis of the coming of Moshiach.

Since this is so, then we find that the way to bring Moshiach is by adding in simcha, simcha b'taharasa, simcha that will immediately bring Moshiach Tzidkeinu.

How could it be that over all the generations they didn't make an effort to bring Moshiach with simcha? They did all they could do to bring Moshiach, even crushing the Crown Jewel in the king's crown, etc. [a metaphor for spreading the teachings of Chassidus], in order to get a drop in the King's mouth[...]

We could say as a simple explanation that when we are found in the doubled and redoubled darkness of golus, when all Yidden are in golus, and the shechina is in golus, it is understood that due to the amount of pain of golus, that simcha b'taharasa is not relevant.

But never the less, since in the end we are obligated to bring Moshiach--there is no choice but to bring Moshiach through simcha, simcha b'taharasa.

Regarding the difficulty to bring about a feeling of simcha b'taharasa in the darkness of golus--since we are obligated to bring Moshiach Tzidkeinu, then we must say that at the end of golus mamash--they give the special powers to be able to have simcha b'taharasa, and the explanation--this simcha is generated by contemplating that mamash immediatly Moshiach is coming, and then the entire world will be in ultimate simcha, and therefore, there is already a feeling of simcha b'taharasa (a taste and sampling of the simcha of the geulah).

And the main thing--that instead of lengthy discussion, etc., they will begin to actually do it: to go out and declare and announce about the special increase in simcha in order to bring Moshiach, and certainly through this Moshiach will actually come mamash, and with the createst alacrity, "in the blink of an eye". Try it and you will be convinced!!
