The pulse knocks and beats in a person. Sometimes, it beats in a person and prompts him to God’s service, as in (Song of Songs 5:2), “The sound of my beloved knocking.” And sometimes, it prompts a person to sin, God forbid.
This is because the pulse comes from the breath, and the breath comes from the air by means of speech. Depending upon speech, such is the nature of the pulse; for good or the opposite.
הַדֶּפֶק דּוֹפֵק וְנוֹקֵשׁ בָּאָדָם. לִפְעָמִים הוּא נוֹקֵשׁ בָּאָדָם וּמַזְכִּיר אוֹתוֹ לַעֲבוֹדַת הַשֵּׁם יִתְבָּרַךְ, בִּבְחִינַת (שיר השירים ה׳:ב׳): קוֹל דּוֹדִי דּוֹפֵק; וְלִפְעָמִים הוּא מַזְכִּיר אֶת הָאָדָם לַעֲבֵרָה, חַס וְשָׁלוֹם,

כִּי הַדֹּפֶק בָּא מִן הַנְּשִׁימָה, וְהַנְּשִׁימָה בָּא מִן הָאֲוִיר עַל־יְדֵי הַדִּבּוּר, וּכְפִי הַדִּבּוּר, כֵּן נַעֲשֶׂה הַדֶּפֶק, אִם לְטוֹב אוֹ לְהֶפֶךְ:
