This concept in a person’s Avodas Hashem is the study of Torah in a manner which can be compared to ‘Engraved Letters’ which is when the person who is studying the Torah is united with the Torah as one entity. This idea can even be explained to a child, because as long as his existence is an existence of Torah, then even in his sleep he will dream matters of Torah etc.
And we can connect this to the concept of: וְּהַחַי יִתֵּן אֶל־לִבוֹ “The living should give it to his heart” in other words ‘take it to heart’. Because true giving as the Talmud says: “Everyone who gives a gift, gives it generously.”
If so, then he gives to his heart in such a manner that his whole heart becomes an existence of Torah.
This can be connected with an explanation from the Rebbe’s Father in his comments on the Zohar on our Parsha. That the word חק meaning ‘Statute’ [also from the word ‘Chakikah’] is spelled with the letter Ches (ח) and the letter Kuf (ק). both of which are very similar to the letter Hey (ה). The difference is only that the left leg from the letter Hey is shorter than the right leg of the letter Hey. Whilst, with the letter Ches the top of the left leg extends upwards to become equal to the right leg. Whereas with the letter Kuf the bottom of the left leg extends downward as is explained.
