## Introduction
This treatise is directly related to the **Dvādaśāṅga Śruta**, which was taught by the last Tirthankara, Bhagwan Mahāvīra, and compiled by his chief disciple, Gautam Ganadhara. The twelfth anga of the Dvādaśāṅga Śruta is **Dṛṣṭivāda**. It has five divisions: 1) **Parikarman**, 2) **Sūtra**, 3) **Prathamānuyoga**, 4) **Pūrvagata**, and 5) **Cūlikā**. Among these, the **Pūrvagata Śruta** has fourteen divisions: 1) **Utpādapūrva**, 2) **Aprāyāṇīya**, 3) **Vīryapravāda**, 4) **Astīnāstipravāda**, 5) **Jñānapravāda**, 6) **Satyapravāda**, 7) **Ātmapravāda**, 8) **Karmapravāda**, 9) **Pratyākyānapravāda**, 10) **Vidyānuyoga**, 11) **Kalyāṇapravāda**, 12) **Prāṇāvāya**, 13) **Kriyāviśāla**, and 14) **Lokabinduśāra**. These fourteen **Pūrvagatas** were so extensive and important that they encompassed the entire **Dṛṣṭivāda** anga, and through them, the entire **Dvādaśāṅga Śruta**, including the eleven other angas, was understood.
This treatise originates from the tenth **Vastu** of the fifth **Jñānapravāda Pūrvagata**, on the third **Pējjadosapāhuḍ**. The term **Pējj** refers to **Preyas** or **Raga** (attachment), and **Dos** refers to **Dveṣa** (aversion). Since the four **Kaṣāyas** (poisons) like anger, and the nine **Kaṣāyas** like laughter, are categorized as **Raga** and **Dveṣa**, the original name of this treatise is **Pējjadosapāhuḍ**, and its alternative name is **Kaṣāyapāhuḍ**. The **Cūrṇikāra** (commentator) himself mentions both names and their significance in the twenty-first and twenty-second **Sūtras** of the first **Adhikāra** (chapter) called **Pējjadosavihatti**.
This treatise is named **Kaṣāyapāhuḍ** because it contains verses describing the various states of **Kaṣāyas**, and its Sanskrit equivalent is **Kaṣāyaprābhṛta**.
## Brief Introduction and Importance
This treatise describes the **Raga-Dveṣa** transformation of **Kaṣāyas** like anger, their nature, state, sections, and regional distinctions, their bondage and transition, their rise and stimulation, their use, their synonyms, and their four types of locations based on time and emotion. It then explains how the absence of a particular **Kaṣāya** leads to the emergence of **Samyagdṛṣṭi** (right faith), and how the destruction and pacification of **Kaṣāyas** lead to **Deśasamyama** (control over the senses) and **Sakalasamyama** (complete control). In short, this treatise explains the various types of **Kaṣāyas** and shows the path to their eradication.
The **Kaṣāyapāhuḍ** is composed in **Gāthā Sūtras**. These **Gāthā Sūtras** are extremely concise and contain profound meaning. Many **Gāthās** are only in the form of questions, which introduce the topic to be discussed.
+ **Pūrvagatas** are the teachings that precede the **Angas**, which are the teachings related to conduct and the answers to questions asked by others. Since the teachings of the **Tirthankaras** were heard by the **Ganadharas** and compiled in the form of twelve **Angas**, they are called **Dvādaśāṅga Śruta**.
