So does one man’s heart to another.
(מג) וְעַתָּ֥ה בְנִ֖י שְׁמַ֣ע בְּקֹלִ֑י וְק֧וּם בְּרַח־לְךָ֛ אֶל־לָבָ֥ן אָחִ֖י חָרָֽנָה׃ (מד) וְיָשַׁבְתָּ֥ עִמּ֖וֹ יָמִ֣ים אֲחָדִ֑ים עַ֥ד אֲשֶׁר־תָּשׁ֖וּב חֲמַ֥ת אָחִֽיךָ׃ (מה) עַד־שׁ֨וּב אַף־אָחִ֜יךָ מִמְּךָ֗ וְשָׁכַח֙ אֵ֣ת אֲשֶׁר־עָשִׂ֣יתָ לּ֔וֹ וְשָׁלַחְתִּ֖י וּלְקַחְתִּ֣יךָ מִשָּׁ֑ם לָמָ֥ה אֶשְׁכַּ֛ל גַּם־שְׁנֵיכֶ֖ם י֥וֹם אֶחָֽד׃

(לה) וַיָּקֻ֩מוּ֩ כׇל־בָּנָ֨יו וְכׇל־בְּנֹתָ֜יו לְנַחֲמ֗וֹ וַיְמָאֵן֙ לְהִתְנַחֵ֔ם וַיֹּ֕אמֶר כִּֽי־אֵרֵ֧ד אֶל־בְּנִ֛י אָבֵ֖ל שְׁאֹ֑לָה וַיֵּ֥בְךְּ אֹת֖וֹ אָבִֽיו׃
It even works from a long distance.. this is why Yaakov would not be consoled.
(8) For though Joseph recognized his brothers, they did not recognize him.
8
ויכר יוסף את אחיו. Joseph recognised his brothers. Joseph had no trouble recognising his brothers since they all wore beards when he left them. Although it is normal for acquaintances who have not seen each other for a long time to recognise one another, i.e. that as soon as one person recognises the second person, he in turn suddenly is able to recognise the first person also, this was not the case here. Normally the heart communicates secrets as we know from Proverbs 27,19 "man's heart will be reflected by his counterpart;" the Torah reveals that in this instance this phenomenon did not work. The reason was that Joseph's exalted position stifled any glimmer of recognition there might have been on the part of the brothers.
Rav Hoffman: "People have setup mental blocks which makes them unreceptive to the feelings that other people send them. Deep in their hearts, they do sense these feelings, but they repress them from their consciousness." (Blockage in water pipe mashal) .. What was the brother's mental block? They did not want to believe his dreams could be true.
