The main goal of Ayurveda is to prevent and treat diseases in patients as well as keep healthy people healthy. Both the body and disease are dependent or caused by food, wholesome and unwholesome food are responsible for happiness and misery respectively as the quote says - Ahara Sambhavam Vastu Rogascha Ahara Sambhavam.1 The key to health and disease does not lie in the application of drugs or chemicals or special therapies but in the prime factors i.e. Aahara, Nidra, Brahmacharya which are pillars of Ayurveda. Aahara has been termed as Mahabhaishajya by Kashyapa can be used as preventive tool in various disease. Ayurveda also focuses on combination and compatibility of food items, their quantities, how they are prepared and how Apathya affects manas, prakruthi and environmental factors of a person. Pathya is not only about food it is also about following seasonal as well as night regimen. Pathya is described according to Dosha, Dushya, Deha Prakriti, and Vyadhi when we choose a diet for a disease based on pathya kalpana it helps to improve the action of the Aushadhi and fights against roga uthpatti karanas and does srotho shuddhi. Pathya is important for swasthya rakshana as well as for dehaposhana. The word Chakshu means which illuminates the objects and enlightens the mind about its details which is situated in eyeballs, when we talk about pathya apathya importance of the word chakshushya can be highlighted, pathya for Akshi can be explained as chakshushya and apathya as achakshushya hence an attempt is made to extract the necessary information about both pathya and apathya in Nethra roga.
