This Smriti highlights the four principal topics i.e. method of repentance, renunciation of indigo, method of purification, food/meals (description of).

This Smriti stresses on the methods of repentance. It discusses the gravity of the sins committed and accordingly prescribes the vow to be observed. All types of cleanliness and purity are discussed here i.e. Rajaswala (women having menstrual cycle), birth and death etc. Angirasa has suggested repentance even for untouchability, killing a cow, intoxication, use of indigo etc.

This text also recommends repentance for the sins, faults committed in the process of attaining the four attainments. That person who fulfills the vow carefully is emancipated from all sins.

Meaning : The Brahmins, Kshatriyas and Vaishyas should observe the Chandrayana, Krichra and semi- Krichra vow if they partake boiled food prepared by the following people i.e.washe, cobbler, Nata, Buruda, oarsman, Bheda and Bhilla.

One becomes radiant if one donates Kashtha (wood) in the winter season as there is an inherent quality of producing fire by Kashtha. Moreover it also enhances ones knowledge and fortune. By donation fuel in winter one becomes successful in war.

Sage Angirasa states that one should not partake food offered by the king as by doing so the radiance of the king is attenuated. Due to the gradual attenuation the person starts becoming unsuccessful. Sage Angirasa has even stated the sins incurred because of the use of indigo which is a novel topic not present in other Smritis.

Meaning: By wearing blue clothes all the five religious sacrifices, holy bath, donation, name recitation, religious sacrifice, study of the Vedas and pacification of deceased ancestors become fruitless.

If one eats food cooked by kindling the wood of indigo, one should vomit out everything and should take Panchagavya. One should repent by observing the Chandrayana vow if one eats food grown in the indigo fields. The sage opines-

Wherever indigo is planted, the land becomes impure for the next twelve years. After twelve years the land becomes pure again.

In today's times the teachings of sage Angirasa are not fully applicable but are being followed at times partially. The prohibition of indigo is absolutely unacceptable today. Indigo is only grown now in South Africa. The impurity coveted to menstrual cycles etc. is accepted till date. Despite being small, this Smriti is very useful for mankind for preservation of righteousness.
