avahārika सांव्यवहारिक and A-sarivyavahārika असांव्यवहारिक -Those that are produced from the original sūkşma (in corporeal) type of nigodas into the rest of the types of Jivas i-e Prithvi Kāyika, Ap Kayika etc, are known as Sãiñvyavahārikas on account of their contact with Prithvi etc. And those that reside in the suşma nigoda right from the beginning are known as A-sāmvyavahārika in absence of any such contact.
Now, the question is whether these nigodas can ever come to the category of Sāmvyavahārika, from that of the A-sämvya vahāka. It is said in Visesaņāvati That those that are found to have come from the category of Sāmīvyavahärika are, really speaking obtained from the original category of Vanaspati-käya.
From amongst the Sānivyavaharikas there are some which return to the original state of sūksma (in-corporeal) nigodas; but even in that condition, these nigodas do not cease to be Samvyavahārika on account of their falling into the said contact with Prithmi Kaya etc.
According to the Bhagavati Sūtra, the life of Sūksma nigoda has been measured as covering innumerable Avasarpiņi and Utsarpiņi ages.
The Āgamas give the longevity of the Bādara type of nigodas as seventy crore crores of Sāgars. The age of Sadhāraņa (General) type of Vegetable-bodied Jivas is measured as 21 times their Bādara (corporeal) and Sūkşma (in-corporeal) lives together, as said in Panca Samgraha.
The term Sädhāraṇa here includes those that are free from distinctions like sūkşma bādara, paryāpta (completely developed) and a-paryāpta (not completely developed) Ārya Syāmācārya has also supported the above-stated view in Prajna-panā (Pannavanā) Sūtra. The term "golā” (spheres) is used because on a small region equal to the point of a hair, innumerable nigodas are oxisting, and in each nigoda there are ananta (infinite) Jivas.“
