The Book of Aṟam is the most important of all the books of the Tirukkural and is considered the most fundamental. The book exclusively deals with dharma, which is common to the entire work of the Tirukkural, thus providing the essence of the work as a whole. An exemplification for this is found in verse 34 of
Purananuru, where its author
Alathur Kilar refers to the entire work of the Tirukkural by simply calling it as 'Aṟam'. In a practical sense, the Book of Aṟam deals with the essentials of the
Yoga philosophy by expounding the household life that begins with
compassion and
ahimsa, ultimately leading to the path to
renunciation. The Book of Aṟam contains the first 38 chapters of the Kural text, all dealing with fundamental virtue. The first four chapters, known as the introductory chapters, include 40 couplets on God, rain, characteristics of a righteous person, and assertion of virtue. The remaining chapters with 340 couplets are addressed to the common man or a householder, which includes 200 couplets on domestic virtue and 140 couplets on higher yet most fundamental virtue based on
grace,
benevolence and
compassion. All the couplets in the book essentially mandate the ethics of
ahimsa (
non-violence),
meatless diet,
casteless human brotherhood,
absence of desires, path of
righteousness and
truth, and so forth. ;Book One—Virtue (அறத்துப்பால்
