Nightfall can cause weakness? 

Diet plays a prominent part in keeping up Brahmacharya. Purity of food brings in purity of mind. That power which connects the body and the mind is present in the food that we take.

Onions and garlic are worse than meat.

Salt is the worst enemy. Too much salt excites passion.

Giving up of salt helps you in controlling the tongue and thereby the mind and all the other Indriyas.

They should be very careful about their night diet. They should never overload the stomach at night. Overloading is the direct cause for nocturnal emissions.

Control of tongue is a sine qua non if you want to control lust, if you want to observe the vow of Brahmacharya. The tongue must be controlled first. Then it will be easy to control the passion. There is intimate connection between the tongue and the organ of generation. Tongue is an organ of knowledge. It is born of the Sattvic portion of the water-Tanmatra. The organ of generation is an organ of action. It is born of the Rajasic portion of the water-Tanmatra. They are sister organs as the source is the same. If the tongue is stimulated with Rajasic food, at once the reproductive organ also gets excited.

Fasting controls passion. Fasting destroys sexual excitement. It calms the emotions. It controls the Indriyas also. Fasting is a great Tapas. It purifies the mind. It destroys a great multitude of sins. All diseases take their origin in overeating.

Many young men are troubled by wet dreams or nocturnal emissions and spermatorrhoea. This dire disease, spermatorrhoea, has eaten away the very core of the heart of many brilliant youth, who were once very promising students during the beginning stages of their educational career. This terrible scourge has sapped the vitality or the very essence of many students and even grown-up people and has made them physical, moral and spiritual bankrupts. This deadly curse has stunted the growth of many young people and made them bemoan their past ignorant, vicious habits. This wretched malady has blighted the hopes of many a young person and brought despair, gloom, shattered health and dilapidated constitution.

Avoid late suppers. The evening meal should be light and eaten before 6 or 7 p.m. If possible, take milk and fruits only at night. No solid or liquid should be taken after sunset.

A loaded bladder is the cause for wet dreams.

The use of laxatives is not of much benefit as it creates heat in the body.

Sometimes, the discharges take place on account of excess of heat in the body, excess of walking or travel, eating a large quantity of sweetmeats or chillies and salt.

Night pollution generally occurs in the fourth quarter of the night. Those who are in the habit of getting up from bed between 3 and 4 a.m. and doing Japa and Dhyana can never fall a victim to nocturnal pollutions. Make it a point to get up at least at 4 a.m. regularly. Sleep on a coarse bed. Use rough mats. Sleep on the left side. Allow the Solar Nadi, Pingala, to work throughout the night through the right nostril. In acute cases, sleep on the back until recovery.

It is befitting for a celibate to wear always wooden sandals as thereby the semen will be conserved, eyes will be benefited, life prolonged and holiness and lustre increased.

Avoid cinema, novels, newspapers, bad company, evil talks. Do not look into the mirror frequently. Do not use scents or fancy clothings. Do not attend dance or music parties. Do not look at mating of animals and birds.

First, dietary control. There is an intimate connection between self-control and control of the palate or tongue. He who has controlled the tongue has already controlled all the other organs.

Delicious Rajasic food excites the organ of generation. Give up meat, fish, liquor, smoking. Meat can make a scientist, but never a philosopher, a sage or a Sattvic Person. Meat excites the passions.

Without renunciation of woman, it is impossible to have Self-realization.

Those who practice by fits and starts will not derive any benefit. Regularity in the practice is very necessary if one wants to realize the maximum benefits of Asanas.
