[[Indriya Sthana]] deals with the observation of signs predicting lifespan and signs indicative of reduced duration of remaining life (also called ''arishta lakshana''). The word [[Indriya]] literally means organ, sense, force, vigor.<ref>Sanskrit-English Dictionary available from http://spokensanskrit.org/index.php?mode=3&script=hk&tran_input=Indriya&direct=au retrieved on April 19, 2019</ref>. In the present context, it means ''Prana'' or vital life force.<ref>Commentary by Chakrapani on Cha. Indriya 1/1-2 available on http://niimh.nic.in/ebooks/ecaraka/?mod=adhi retrieved on April 19, 2019</ref>. The seat of ''prana'' in the body is ''Sneha'' or ''Ojus''. ''Indriya'' (sense organs) are said to be the ''linga'' (organs) of ''prana''. An important concept discussed in this section is termed ''Indriyadushti'' (damage to the sensory system). A state of perfect health is ''Anirvedovarta Lakshanam'' (i.e., life without any indication or perception of being alive).(Cha.Su.25/40)

===Logical sequencing of chapters===

===Logical sequencing of chapters===

Life begins with the association of consciousness, or the ''atma'', with the five fundamental elements (earth, air, fire, ether, and water, or the ''panchamahabhuta'') and ends in the dissolution of this association. Since this union (that results in a living being) is by no means permanent and since there is always a possibility of dissolution or death anytime, Ayurvedic texts emphasize on identifying certain signs and symptoms that could forebear, with some level of certainty, imminent death. This section is dedicated to such determinants and is structured in the form of 12 chapters.

* Signs and symptoms (''arishtas'') of imminent death can be perceived by specific changes in sensory system (e.g.,  ''varna'' (color), ''swara'' (voices/sounds), ''gandha'' (smell), ''rasa'' (taste), ''sparsha''(touch),along with ''chhaya'' (complexion) and ''prabha'' (radiance)) are addressed in chapters [[Varnasvariyamindriyam Adhyaya]], [[Pushpitakamindriyam Adhyaya]], [[Parimarshaneeyamindriyam Adhyaya]], [[Indriyaneeka]], [[Pannarupiya]] and [[Yasyashyavanimitta]].

* [[Gomayachurniya]], [[Anujyoti]], [[Kathamanasharireeya]], [[Avakshiraseeya]] and [[Sadyomaraneeya]] are chapters that give examples of ''arishta'' that could be perceived on the physical level (or, are ''Bahyakarana'') as well as on the mental, intellectual, and emotional levels (or, afflicting the ''Antahkarana'' ),  with references to ''shakun''( good / bad consequential happening)), ''doota''( messenger), ''swapna'' ( dreams) and miscellaneous  occult sciences. The evidences laid down in these chapters may establish an [[Ayurveda]]-based clinical diagnostic methodology.
