Nidra or Sleep
According to Ayurveda,the state when body and mind body o to rest is called as nidra.Our body continuely goes on working ,the sensory stimuli which have to be accepted, analyzed, acted upon, stored in memory for future use etc done each and every time. This working process of body results in fatigue which again results in inability in perception of stimuli. The bonds between the sensory organs and the mind by prANa vAyu, udAna vAyu, vyAna vAyu, sAdhaka pitta, and tarpaka kapha and rasa dhAtu get depleted. This leads to a state in which the mind retracts itself, known as sleep.

When the mind is afflicted by Tamoguna in night ,there is increase in kapha dosha and natural sleep is inflicted.Kapha dosha is responsible for growth and development of body tissue and increases the immunity.

Anger,aggression,depression etc causes increase of vata dosha which is opposite of tamoguna.Hence person suffering from depression,anger can not sleep clamly in night..

Lack of sleep results in dull feeling all day,laziness,headache,bodyache ,burning sensation in eyes etc.Day sleeping,late sleeping in night,sleeping long also distrubes the whole day routin and gives bad effect on health. Bad sleeping also effects on digestive system,excretory system,circulatory system and other all systems of body.

Strength and misery, nourishment and emaciation, strength and debility, virility and impotence, knowledge and ignorance, life and death – are all dependent upon sleep.

. Good or normal sleep leads to Bad or more/less/disturbed sleep leads to sukha or joy dukha or sorrow poSaNa or growth & development karSaNa or debilitation bala or good strength & immunity abala or decrease in strength & immunity vRSata or good sexual prowess klIbata or decrease in sexual prowess jnAna or knowledge ajnAna or ignorance jIvana or good quality of life and life span ajIvana or short life span.

Day Sleeping is advisiable in summer season.because in this season vAta will have undergone mild increase, dryness is more, and nights are short because it is AdAna kAla.

Awakening in night results in increase in vata dosha which makes the body dry.

Brahmacharya-
The word Brahmacharya means abstinence.The term brahmacharya referes to keep person away from excessive sex. The word brahmacaryA is commonly used in relation to sexual activity. However we must remember that the literal meaning of this word would be “AcAra or practices for the attainment of BrAhman or the merging into the universal consciousness.” This is what brahmacaryA indicates – the engagement in practices which would lead us closer to eternal bliss. And that is why it is described as the third pillar of life and living.

The Ayurveda advised refrain of sexual activities during the academic years called as Brahmacharya ashram while advise the sexual intercourse after the marriage and this is called as Gruhastashrama.Excessive indulgence leads to loss of physical strength,lack of memory and vitality,increase in irritability and also the physiological distrubence in functions of body which leads to vitiation of doshas.

Ayurveda text explain how brahmacaryA is to be practiced in relation to sexual activity. It also gives idea of sex according season and amosheperic condition like that one can indulge in copulation once in two days during spring; once in a fortnight during summer and rainy season; and as many times as one desires (based on one’s natural strength) during the cold seasons of the year.

Ayurveda text also gives the idea about the age. One should not have sexual intercourse with a partner below the age of sixteen or above the age of seventy as this is bad for both partners. For, those below the age of sixteen will not have attained full development of all the tissues of the body and hence if they indulge in copulation, their body dries up quickly while for those above seventy, if they indulge in copulation, they collapse .

Copulation should always perform with a pleasant mind with a partner of one’s liking adopting the suitable posture anointed with good smelling cosme
Physical Brahmacharya and Mental Brahmacharya It is very necessary that should be pure in mind if wish to be a Brahmachari. Mental Brahmacharya is more important. It may succeed in Physical Brahmacharya, but must succeed in mental Brahmacharya also. That state of mind where in no single sexual thought enters the mind is termed mental Brahmacharya. If thoughts are impure, the sex impulse will be very strong. Brahmacharya depends upon regulating the whole course of life. “Smaranam Keertanam Kaileh Preshanam Guhayabhashanam. The eight bricks in Brahmacharya Samkalpoadhyavasayasch Kriyanirveritireva Cha.

Ethanmaithunamshathngam pravadanti maneeshinam.” (Yagyavalkya Smriti) It should carefully avoid the eight kinds of enjoyment, namely, Darshana or looking at women with passionate resolve, Sparshana or touching them, Keli or play, Kirtana or praising the qualities of the other sex, Guhya-Bhashan or talking in private, Sankalpa or determination, Adhyavasaya or nearing the other sex with the desire for gratification and Kriyanivritti or the actual sexual act. These eight kinds of enjoyment are eight kinds of breaks, so to say, in the current of Akhanda Brahmacharya practice. It must avoid these eight interruptions with great care, sincere exertion and vigilant circumspection
