It appears from this weeks Parsha that indeed we can.
At Har Sinai the Posuk tells us: Ve’Chol Ha’Om Royen Es Hakolos V’Es Halapeydim. Rashi Z”L explains that Bnei Yisroel ‘Roiyen Es Hanishma”, they saw the sounds- that which is heard- the Aseres Hadibros emanating from Hakodesh Boruch Hu and Moshe Rabbeinu.
The Sfas Emes Z”L asks how is this possible, how can we see a sound?
Answers the Sfas Emes that to appreciate this, we need to understand the differing characteristics of seeing and hearing.
When one sees an object, the object and stimulus remains external to the viewer and is not incorporated within the person.
On the other hand, when one hears a sound, it is internalized and becomes one with the person.
At Har Sinai, says the Sfas Emes, when Hashem said the words “Ohnochi Hashem Elokecho” Bnai Yisroel saw their shoresh chiyuso and as a part of their ‘Nishmas Hashem’ that resides within every Jewish soul, the Mahus of every Jew, the “Pintele Yid”. Their response was “Na’aseh, Ve’Nishmah!”, the external actions required to fulfill Mitzvos became internalized and woven into the Neshamah of every Yid.
How is Emunah acquired asks Harav Gamiliel HaKohen Rabinowitz, Shlita. By constantly speaking of Emunah; the external of speech will internalize and make it a part of us. Rav Gamliel brings the Posuk:
“He’Emanti Key Adahber Le’ma-an Tesaper B’oznei Bincho U’ben Bincho Es Ahsher His’ahlalti Be’Mitzrayim Ve’Es Ohsosei Ahsher Samti Bom Vee’Datem Key Ani Hashem.”
Emunah is strengthened by constantly speaking of it, “He’Emanti Key Adahber…” to the point where it becomes part of you.
