The world is in need of a purified atmosphere.
Purified air comes only through words of Torah.
Words of Torah offer protection in general and for each individual in particular.
The division of the Six Orders of Mishna (the [formerly] Oral Law of Judaism) for memorization is intended for "when you walk on the road."
The Mishna or two recited from memory wherever one may be, in whatever sort of place he may be, will illuminate the bond between Israel and G-d.
The letters MiSHNa are the same as NeSHaMa (soul).
It is extremely difficult to find the words to express the tremendous benefit, with G-d's help, in the general and individual protection that constant repetition of Mishna will bring.
And there are no words to describe the tremendous gratification one thereby gives the Creator, may He be blessed.
As the Rebbe wrote, this is a powerful segulah (physical action bringing spiritual blessings) for protection and purification of ones place. Further, kabbalistic and hassidic thought teaches that sparks of divinity that are mixed into the world may be released or gathered up through the recitation of Torah (and Mishna is a recommended method).
The world is waiting for you to walk by with these words on your lips!
For an example Mishna, here's an extensive hebrew/english edition, and here's a sample page.
