Chasidut for Megillah 33:15

We find in the Torah that the details of the life of Yaakov are not written clearly, but are alluded to, as is written in Megilla 17A: Why were the years of Yishmael counted? In order to relate the longevity of Yaakov's life - to teach us that he was blessed (by Isaac) at the age of 63, and that he was 14 years in the study halls of Shem and Ever (although this was never explicitly stated anywhere in the Torah itself). This is true especially when he arrived in Egypt and said to Pharoah: The days of my sojourn are 130 years, and since we know that he lived 147 years old, we know from this that he was in Egypt for 17 years. If this is the case his age is obvious, and there is no need for us to be told his final age of 147 years. There is therefore no need to mention both his final age or his 17 years that he lived in Egypt (we could derive one from another quite simply (ed))!

And he dreamt, etc, and Yaakov woke up from his sleep and said 'Surely H' is present in this place, and I did not know it! etc This is none other than the abode of God, and that is the gateway to heaven.' (Gen. 28:16-17) And there is a midrash that Yaakov awoke from his mishnah (Bereishit Rabbah 69:7). And this is surprising, and it appears to me [that the explanation is] that it is known that the essence of the service of a person, to come to the objective of completeness in their service to the Holy One of Blessing, to attain the Blessed One's Godliness, happens through Torah and Tefilah, and one cannot exist without the other. This is because an Am Haaretz cannot be a Hasid (Pirkei Avot 2:5), and also, Torah alone will not complete one's soul, as the saying of the sages z"l "anyone who says he has nothing other than Torah, has no Torah" (Yevamot 109b:4), since obviously through doing Torah for its own sake one can come to a great holiness when one learns for its own sake, and clings to one's life-force [nefesh], spirit [ruach] and soul [neshamah] through the letters of the Torah. However, one cannot come to the essence of Awe and Love and Longing in one's service to the Holy One of Blessing , and to grasp Godliness [with Torah alone], rather, through Tefilah, with self-sacrifice and enthusiasm as it is know from the sacred books. And behold the saying of the sages z"l is known: "and he encountered the Place, meaning, he fixed the evening prayer" (Brachot 26b:7) - behold he didn't know until that moment the secret of Tefilah, how great it is, and we find that Yaakov hid in the study house of Shem and Ever (Megillah 17a:5) and learned Torah, and we see that he knew the secret of Torah, however he did not discover God's Godliness until this moment, when it was revealed for him after he stood at the secret of Tefilah. And this is the explanation for the midrash "and he awoke from his sleep - from his mishnah" - they wanted to say from his Torah, that was awaken through this Tefilah, and he understood that he had not reached complete understanding through Torah alone, and so he said 'behold, there is Hashem in this place', meaning, through this tefilah he was able to understand more deeply the revelation of Godliness than he had until that moment, which was through Torah alone. "And I didn't know" this secret "this is but the House of Elokim", meaning through Tefilah, self-awakening and enthusiasm a persn can come to Higher Awe, which is called in the language of our sages z"l 'pity on one who has no courtyard etc' (Shabbat 31b:1). "And this is the gate to heaven" that Tefilah is the essence of the gate to heaven, to come to an understanding of Godliness and awe of heaven, a good treasure, since "awe of Hashem is God's treasure" (Isaiah 33:6) and pay attention to this, because it is correct.
