## Editorial: Jyotiganarajprajnapti, i.e., Chandraprajnapti and Suryaprajnapti
[From the First Edition]
**Sutra-patha of Suryaprajnapti**
If one were to compare the original sutras of the Suryaprajnapti presented here with the previously published Suryaprajnapti, they would not match exactly. This is because the sutras in this edition have been supplemented with several additional sentences. However, the authenticity of the sutra-patha remains intact. Only experts in the Agamas will be able to understand the justification for the arrangement of the sutra-patha.
**Introduction to the Two Upangas**
Apart from minor differences, Chandraprajnapti and Suryaprajnapti are completely identical. Therefore, an introduction to one automatically introduces the other.
* The name determined by the compiler is Jyotiganarajprajnapti.
* Initially, the combined name in circulation would have been Chandra-Suryaprajnapti. Later, the two Upangas were divided and named Chandraprajnapti and Suryaprajnapti, which are still in use today.
* Each Prajnapti has twenty Prabhritas, and each Prajnapti has 108 sutras.
* From the third Prabhrita to the ninth Prabhrita, i.e., in seven Prabhritas, and from the eleventh Prabhrita to the twentieth Prabhrita, i.e., in ten Prabhritas, there are no 'Prabhrita-Prabhritas'.
* Only the first, second, and tenth Prabhritas have 'Prabhrita-Prabhritas'. - According to the combined number, there are no 'Prabhrita-Prabhritas' in seventeen Prabhritas. Only three Prabhritas have 'Prabhrita-Prabhritas'.
