The classification of animals by the Jainācārya into sthalacara ( terrestrial ), Jalacara (aquatic) and Khecara (aerial)91 beings, etc. throws light upon their habitat and ecology to which they could grow and adapt and make themselves better fitted in their survival.
The study of life of beings was made by the Jainācāryas in relation to environment, so climatic conditions have been described by them under the term Rtu '92 It has been sub-divided into prāvșt or varsā (Rainy season – Śrāvanādi or Asayujādih ), Sárad (Mārgasirşadhiḥ = Autumn), Hemanta (Māghadih - Winter ), Vasanta ( Caitrādih=Spring ) and Grisma (Jyesthādih - Summer ).93 The study of life in relation to environment probably began from the Vedic period94 and climatic conditions were similarly treated under the same term “Rtu' (Season ) which was first sub-divided into three seasons, viz. Vasanta (Spring), Grīşma (Summer) and Sarad (Autumn ).95. Rtu bas also been sub-divided into five seasons, viz. Vasanta, Grisma, Varsā, Sárad and Hemantaśiśira 96 or sometimes into six seasons 97by separating Hemanta and Sisira.
