Eat when you are hungry. Do not eat anything between meals. Eat slowly in a calm mood. Chew properly. Eat moderately. Avoid many combinations of food. Drink a glass of water one hour before or after food, never with a meal. Fast on Ekadasi. Eat nothing before 9 a.m. or after 7 p.m. Take care of your teeth. Just before or after a meal, avoid all exertion, mental or physical. Relax at least for half an hour. A long brisk walk is beneficial. Paschimottanasan, Halasan, Bhujangasan, Salabhasan, Dhanurasan, Mayurasan¾ these Yogasans will remove indigestion. Depression of mind, cares, worries and anxieties also affect the stomach. Be cheerful. Be regular in your Japa.
Lust is but a natural tendency of the mind. The best method to check the impulse is the way of intense and deep Vairagya by a study of religious books, by constant Satsang with Mahatmas (noble souls), by self-enquiry or "Who am I?" enquiry, by close observance of the ways of the world, and by an understanding of the diseases and the spiritual degradation that result from over-indulgence. Remember the saying of the Lord in the Gita:
Trividham Narakasyedam Dvaram Nasanmatmanah
Kamah Krodastata Lobhas Tasmat Etat Trayam Tyajet
(Ch. XVI-21)
Practice the chief Asans and Pranayam as detailed in my books "Yoga Asanas" and "Science of Pranayama". Do intense Japa to the point of self-forgetfulness. Treat womankind as the manifestation of the Devi, the adorable Mother Divine. Maintain Matru Bhav in your dealings with the other sex. Give up looking at the face of a woman, but look at her feet to avoid room for evil thoughts to crop up or indiscriminate deeds to arise. Take cold water bath always. Contro1 the tongue. To give leniency to the tongue means to allow free access to lust to trouble the being. Always engage yourself in pure and noble thoughts. Realize the glory of Brahmacharya by studying the lives of Hanuman, Ramdas, etc. Check yourself as per the details given in my book, "How to Get Vairagya". Reduce wants and desires. In proportion to the reduction of the egoistic self, all negative tendencies will disappear.
Scriptures, and the personages and episodes in the scriptures, are as true as God Himself. The former definitely and unambiguously say and propound that all the thirty crores of Devatas as envisaged in Hinduism have their abode in the frame of the cow, as in the Basil plant (Tulasi). The cow is boldly proclaimed in the scriptures as one of the objects of Dana (offering) for the uplift of the soul when the Prana departs from the body of a human being. The cow is really worthy of our adoration. Pancha Gavya (the milk, curd, Ghee, urine and dung of a cow) are ordained to be taken in for Prayaschitta at the commencement of certain Vratas like Rishi Panchami. Any number of instances can be cited regarding the holiness of a cow. Go-puja (cow worship) is as much fruitful as Sannyasi (Sadhu) Puja. It is equal to, if not more than, Sakala Devata Puja (worship of all deities). Such being the case, cow-slaughter (Go-Vadha) is condemnable without hesitation.
