== Constitution and Properties of Matter ==
Chemistry involves the study of fundamental properties of matter and atoms. and their inter-relationship. The Ayurvedic period constitutes the most flourishing and fruitful age of ancient India relating to the accumulation and development of chemical sciences which at that time was closely associated with medicine. The physical and chemical theories were intricately associated with the [[Srshti Siddhanta (सृष्टिसिद्धान्तः)|srshti siddhantas]] propounded in the darshana shastras most importantly Samkhya and Vaiseshika. Ayurveda was founded on the theories of cosmic evolution in [[Ayurveda and Darshanas (आयुर्वेदः दर्शनानि च)|Darshanas]].
Chemistry dealt primarily with the composition and changes of matter and the underlying principles were deduced in a systematic and logical way purely based on thoughts with little or no experimental proofs. Yet many such theories, the products of intellectual perfection and sublime intuition, stand in good comparison with some of the most recent and advanced scientific ideas of the present time. Here we come across a few ancient concepts with particular reference to srshti (theories of cosmogenesis) and origin of jagat (universe) with respect to matter and particles and their connection with chemistry.
* Rig veda (10.121.1) mentions Hiranyagarbha reflecting the concept of cosmic egg and origin of universe from an egg.
* Chandogya Upanishad mentions about expansion of universe from an embryonic stage
* Samkhya siddhanta (supported by Yoga sutras of Patanjali) describes the principles of conservation, transformation and dissipation of energy. Additionally the conception of space (desha) and time (Kala) are also discussed.
* Vaiseshika siddhanta propounded the particulate theory of matter ([[Padarthas (पदार्थाः)|Padarthas)]] to describe the nature of different substances that make up this jagat.
Thus broadly the origin and composition of matter
