In order to realize the immediate revelation and coming of Moshiach - each and every Jew (the men, whether they are dwellers in the tent (Yisachar) or men of business (Zevulun), and the women and children, each one according to his ability) should increase their learning of Torah, particularly the subjects of Moshiach and Redemption.
It would be even better if they would learn (in public) with ten others because, in addition to the advantage that "ten who sit and occupy themselves with Torah, the Divine Presence dwells among them," there is a particular advantage when learning about Moshiach and the Redemption in public. Such public learning affects the excitement and the heart-felt joy through which comes an increasing desire and anticipation for the coming of Moshiach.
In addition -- and this is obviously most essential - one should increase the quality of one's observance of mitzvos; in particular one should enhance one's fulfillment of the mitzvah of tzedekah (comprehensive of all the mitzvos) with distinction, for it "draws near the Redemption."
It is proper and correct to connect the increase in tzedekah with an increase in the Torah concerning Moshiach and Redemption; by giving tzedekah with the intention to bring close and hasten the Redemption. This intention itself constitutes learning Torah in matters of Redemption. When one thinks of from time to time the saying of our Sages, of blessed memory, "great is tzedekah for it brings near the Redemption," it constitutes learning matters of Moshiach and Redemption.

- Therefore, those who want to learn in depth, and in the give and take fashion of scholarly discourse (and to even contribute original Torah ideas about Moshiach and Redemption) in a quiet and peaceful setting, and therefore prefer to learn by themselves or with a partner, should still try (from time to time) to also join the learning of ten; this way they will also have the advantage of learning with ten (as mentioned in the text).
