There is more than one answer to the question. 1) The Torah, given by God through Moses (Exodus 24:12), contains the laws of Judaism.
2) The Talmud clarifies the details of the brief laws in the Torah.
The Torah, with all of its hundreds of commands. The laws themselves have various reasons. Some (such as the Passover) serve to reenact or remember events of our history.
Some (such as saying the Shema-prayer) serve to reiterate our belief in God.
Some of the laws (such as those of ritual purity and kosher food) serve to sanctify us.
Some (such as the laws of torts) serve to maintain an orderly society.
Some (such as the law against breaking a vow) serve to prevent bad character traits.
Some (such as the command to offer help) serve to engender good character traits.
And all of the commands serve to subjugate us to God's will (especially those commands for which no explanation is easily apparent).
Some examples of the commands:
Putting on Tefillin (a.k.a. phylacteries) in the morning
The sukkah-booth during Sukkot
Avoiding leavened products in Passover
Not eating on Yom Kippur
Not working on the Shabbat
Paying workers on time
Marital rights for one's wife
Counting the days of the Omer
Returning lost objects when feasible
Wearing the tzitzith-garment
Learning Torah
Marrying and having children
Educating one's children in Judaism
Giving tzedakah (charity)
Honoring one's parents
And many more.
Note that the Torah "as is" isn't exactly what Judaism observes. Rather, It's the Torah together with the details provided in the Talmud, which is the Oral Law that was handed down together with the laws of Moses. Otherwise, the verses of the Torah often lack enough detail to be fulfilled as is.
