## First Karma Granth, Chapter 45
**Pratyay Avadhigyan** is the knowledge that does not require any austerities like **samyama**, **tapa**, etc. This type of **avadhigyan** is present in **devas** and **narakas** and remains with them throughout their lives.
**Gunapratyay Avadhigyan** is the knowledge that is not present at birth but arises after birth due to the power of **yama-niyama**, **vratas**, and other austerities. This type of **avadhigyan** is only present in humans and **panchendriyatyantr** beings.
**Difference in Avadhigyan**
**Bhavapratyay** and **Gunapratyay**
Although **bhavapratyay avadhigyan** also generally requires **kshayopasham** (the complete cessation of karmas) like **gunapratyay**, the emphasis here is on the **bhavas** (states of existence) due to the difference in the cause. There are certain species of beings who, upon birth, acquire the necessary **kshayopasham** and the **avadhigyan** that arises from it. These beings do not need to perform **vratas**, **tapas**, etc. in that life to attain the **kshayopasham** necessary for **avadhigyan**. Such beings, according to their state, develop **avadhigyan** immediately upon birth, and it remains with them throughout their life in that state. For example, birds acquire the ability to fly in the sky upon birth, while humans, on the other hand, cannot fly in the sky simply by being born, unless they use an airplane or other such device.
