"Because Abraham heeded My voice and kept My charge: My commandments, My decrees, and My teachings." This includes both the Written Torah and the Oral Torah, as explained by Rashi. Our Sages of blessed memory said (Niddah 61b) that mitzvot will be nullified in the future, etc. says the Ba'al Shem Tov a"h in the name of the Ramban a"h, that in the future, people will attain an understanding of the essence of each mitzvah and the root of the mitzvah's life-force... And just as our Avraham Avinu attained the entire Torah on his own - not that he observed the Torah because of H'shem's command or because it was commanded to him, for the Torah had not yet been given - rather, he attained through his intellect the root life-force of each and every mitzvah, understanding how it is the life of his essence and that he must perform it to give life to his soul in order to cleave to the Life of all life. And so in the future it is written (Isaiah 11:9), "And the earth shall be filled with knowledge [of H'shem] as water covers the sea."

To "make a vow" (in Hebrew, "yedor neder") means to take upon oneself to do or not to do a certain thing. Rebbe Elimelech of Lizhensk, in his book Noam Elimelech, says that the Hebrew word for "vow", "neder", is related to the word "dira", meaning a dwelling. To make a vow, to "yedor neder", therefore, can be interpreted to mean "to create a dwelling place".
It is written that every Jew has a soul which is descended from the source of all Holiness and is intrinsically GDly. To "yedor neder" means to prepare a dwelling place for this G‑dly soul in the upper worlds.
