## Verses 235-240
## Yoga Marga, 311
The duration of the lifespan of an Aharak-kamithakaya-yogi varies from the shortest to the longest. A careless, restrained being who has previously produced many Aharak bodies and attained perfection in the shortest possible time, experiences the shortest lifespan. This is how the shortest lifespan is attained. A careless, restrained being who has never produced an Aharak body before and attains perfection in the longest possible time, experiences the longest lifespan. This is how the longest lifespan is attained.
The shortest lifespan for an Aharak-kayayogi is one moment. A careless, restrained being who is engaged in Manoyoga or Vachanayoga and attains Aharak-kayayoga, dies or enters the original body within the second moment. This is how a lifespan of one moment is attained.
The longest lifespan for an Aharak-kayayogi is an Antarmuhurt. A careless, restrained being who is engaged in Manoyoga or Vachanayoga and attains Aharak-kayayoga, remains in the state of the most excellent Antarmuhurt and attains other yogas. This is how the longest lifespan is attained.
A being who experiences the emergence of an Aharak body has four types of Udayasthan named Karma: twenty-five, twenty-seven, twenty-eight, and twenty-nine. The twenty-five natural Udayasthan are: Manushya-Gati, Tejas-Sharira, Karma-ran-Sharira, Aharak-Sharira, Praharak-Mangopanga, Varna-Chatushk, Upghāt, Aguru-laghu, Panchendriya-Jati, Sthira, Asthira, Shubha, Ashubha, Pradey, As-Chatushk, Sama-Chaturasra-Sansthan, Subhaga, Yashaskorti, and Nirman. When the body is fully perfected, the combination of Parghāt and Prashasta-Vihayogati results in twenty-seven natural Udayasthan. When the Anapan-paryapti is fully perfected, the combination of Ujjhav and Vas-Prakriti results in twenty-eight natural Udayasthan. When the Bhasha-paryapti is fully perfected, the emergence of the Susvara-Prakriti results in twenty-nine natural Udayasthan. These four Udayasthan clearly indicate that the absence of the Sanhanan-karma in the Aharak-Sharira results in the absence of the seven dhatus, including Asthi (bone).
The Aharak-putala emerges from the tenth door, the Shirachhidra, which is located at the eighth part of the front of the hair. Therefore, it is said to be born from the Uttaanga.
