## The Ten Kalpas (Practices of the Ascetics) as described in the Brihatkalpa Sutra, Chapter 10:
1. **Achelkalpa:** Not possessing extravagant clothing, but only modest clothing. Not wearing colored clothing, but only naturally colored (white) clothing. Not possessing valuable, bright clothing, but only inexpensive, ordinary clothing.
2. **Auddeshikakalpa:** Not consuming food or other items that have been prepared for the purpose of another ascetic or lay person, as such food is considered to have a "proddeshik" (purposeful) fault.
3. **Shayatarapindakalpa:** Not consuming food or other items offered by the one who provides a bed.
4. **Rajapidakalpa:** Not consuming food or other items offered by a crowned king.
5. **Kritikarmakalpa:** Performing acts of respect and humility towards those who possess great wealth.
6. **Vratakalpa:** Observing the five great vows or the four yamas. The fourth and fifth great vows are collectively known as "Bahiddhadan" in the four yamas.
7. **Jyeshtakalpa:** One who has received the greater initiation earlier is considered "Jyeshta" (senior). All ascetics are considered "Jyeshta" for the female ascetics. Therefore, one should behave accordingly, treating them as seniors.
8. **Pratikramanakalpa:** Performing daily, regular "Pratikraman" (self-reflection) both in the day and night.
9. **Masakalpa:** While wandering during the Hemant (winter) and Grishma (summer) seasons, one should not stay in any village or town for more than one month. After staying for one month, one should not return to that place for two months. For female ascetics, the duration is two months instead of one.
10. **Chaturmasakalpa:** During the rainy season (Varsha ritu), one should stay in the same village or town for four months and not wander. After Chaturmas, one should not stay in that village and should not return there for eight months (making it a total of twelve months after Chaturmas).
These ten Kalpas are mandatory for the ascetics of the first and last Tirthankaras. For the ascetics of the middle Tirthankaras, only four Kalpas are mandatory, while the remaining six are optional.
The four mandatory Kalpas are:
1. Shayatarapindakalpa
2. Kritikarmakalpa
3. Vratakalpa
4. Jyeshtakalpa
The six optional Kalpas are:
1. **Achel:** Possessing clothing of any type, whether inexpensive or expensive, colored or naturally colored, in any quantity as desired or as available.
2. **Proddeshik:** Not consuming food or other items prepared for oneself, but consuming food or other items prepared for any other ascetic as desired.
3. **Rajapind:** Consuming food offered by crowned kings as desired.
4. **Pratikraman:** Performing regular Pratikraman as desired, but performing Pakkhi, Chaturmasik, and Sanvatsarik Pratikraman is mandatory.
