## Karmavipaka and its Influence on Rebirth
A being reaches its destination of rebirth based on its **karmavipaka**. This process is influenced by **anupurvi** **namakarma**, which acts as a cause. **Anupurvi** **namakarma** pushes a being from its **samashreni** (higher) birth place to a **vishreni** (lower) birth place. If a being's birth place is already in **samashreni**, **anupurvi** **namakarma** does not arise. **Anupurvi** **namakarma** arises in **vakragati** (curved path) but not in **rijugati** (straight path).
The terms **gati-dvik**, **gati-trik**, etc., are used in this context. **Gati-dvik** indicates the presence of two elements: **gati** (path) and **anupurvi** **namakarma**. **Gati-trik** indicates the presence of three elements: **gati**, **anupurvi** **namakarma**, and **ayu** (lifespan).
For example, **narak-dvik** refers to **narak-gati** (path to hell) and **narak-anupurvi** (karma leading to hell). **Narak-trik** refers to **narak-gati**, **narak-anupurvi**, and **narak-ayu** (lifespan in hell). Similarly, **tiryanch-dvik**, **tiryanch-trik**, **manushya-dvik**, **manushya-trik**, **dev-dvik**, and **dev-trik** can be understood in the same way.
**Dvik** refers to the combination of **gati** and **anupurvi** **namakarma**, while **trik** refers to the combination of **gati**, **anupurvi** **namakarma**, and **ayu**.
## Vihayoga-gati Namakarma
**Vihayoga-gati** **namakarma** has two types:
1. **Shubha-vihayoga-gati**: This karma leads to a good gait, like that of an elephant or a bull.
2. **Ashubha-vihayoga-gati**: This karma leads to a bad gait, like that of a camel or a donkey.
