First, Answer my question that if someone has an Aeroplane's ticket in his pocket, then should he will like to travel in a Bus ? Certainly, Not. Like this you should read the below lines and can decide yourself.
Not to loose the True Guru’s Grace
The birth as a human being is very difficult, before taking birth as a human one has to take birth in 84 lakhs ‘yonis’ according to one’s deeds. If someone percives birth as human being he/she has to find a good teacher (guru) to attain eternal happiness and peace in his/her own life. It requires MUCH LABOUR to find a 'poora guru' (complete and perfect teacher), who helps in one’s journey of mind and conduct to attain eternal happiness and peace. In other words , IT IS VERY DIIFFICULT TO GET BIRTH AS A HUMAN BEING AND IT IS MUCH MORE DIFFICULT TO GET BIRTH IN A SIKH FAMILY OR ANYHOW NEARNESS TO ‘POORA GURU’. As we (Sikh) got the nearness of ‘poora guru' (complete and perfect teacher) by our past good deeds, as baani says
'purab likhat likhe gur paeiya' -4th Guru Nanak, Ang 13 Sri Guru Granth Sahib Ji
'Bhag hova gur sant milaya,
prabh abinasi ghar mean payiya' -5th Guru Nanak, Ang 97 Sri Guru Granth Sahib Ji
We could have achieved more benefits from 'poora guru' and can proceed further, but not to WASTE our past hard labour of good deeds BY GOING AGAINST THE SIKH PRINCIPLES.
It is easy to become a Doctor, an Engineer, a Pilot or any other good professionalist but it is very difficult to earn 'Dharma' by making good deeds in our life. So, one should not waste this type of labour by going against the sikh traditions.
The importance of ‘poora guru' is very great, as baani says
'poorea gur ka sun updesh,
parbrahm nikat kar pekh' (Sukhmani Sahib)-5th Guru Nanak, Ang 295 Sri Guru Granth Sahib Ji
Our great Guru directly connects us to the God Almighty and God is in His nature, as even 1st GURU NANAK’s baani says
‘balihari kudrat vasiya, tera ant na jayi lakhiya’-Guru Nanak, Ang 463 Sri Guru Granth Sahib Ji
Japji Sahib’s 1st pauri says ‘Hukam rajai chalana Nanak likhiya naal’ ,as we have to follow His DIVINE WILL and respect the NATURE. -Guru Nanak, Ang 01 Sri Guru Granth Sahib Ji
HAIRS ON THE HUMAN BODY IS BY NATURE, AND GOING AGAINST THIS NATURE COULD ATTRACT HIS DISPLEAURE FOR A SIKH.
The God in his Will and wisdom has created the complete human being. To interfere with the God given body by circumcision, puffing a hole in the ear or nose and cutting or dyeing the hair are prohibited and treated as disobedience to God’s Will. A God fearing person can never prefer his will and wish to prevail over the God’s Will and can never make any alterations in the God gifted boon, which could attract His displeasure.
Guru Nanak Sahib gives the highest place to ‘Nimarta’ (‘hirdey di garibi’) and saying that
‘Naam beej santokh suhaga rakh garibi veas’ -Guru Nanak, Ang 565 Sri Guru Granth Sahib Ji
When a person becomes very humble (having ‘Nimarta’) he becomes prideless and he obeys God’s divine order or His will very happily.
‘Kudrat kare jhano, jot is bhave nanaka hukam soi parvano -Guru Nanak, Ang 25 Sri Guru Granth Sahib Ji
‘Nanak hukme je bujhe ta huame kahe na koe’ -Guru Nanak(Japji Sahib), Ang 1 Sri Guru Granth Sahib Ji
According to the principles of Guru Nanak in Sri Guru Granth Sahib it is also written like that
‘Sabat surat dastaar sira’ -5th Guru Nanak, Ang 1084 Sri Guru Granth Sahib Ji
‘Kar kirpa Apna daras dije jas gavao nis ar bhor,
Kes sang das pag jharao ehoo manorath mor’ -5th Guru Nanak, Ang 500 Sri Guru Granth Sahib Ji
One who loves God, who equally loves His creatures. Guru sahib praises the symbols of ‘sargun sarup’ of Akalpurakh (God) in human being, then says like that
‘Tere banke loen dant risaala, sohne nak jin lamde wala’ -Guru Nanak, Ang 567 Sri Guru Granth Sahib Ji
In whole of Sri Guru Granth Sahibji (Sri Guru Granth Sahib Ji) on almost every Ang (page) there is written about
(i) ‘Kudrat’ (Nature)
(ii) ‘Bhana’ (will of GOD)
(iii) ‘Hukam’ (divine order)
(iv) ‘Nimarta’ (humble and politeness) or prideless
All of the above qualities very clearly implies that every sikh must be keshadhari.
All the sikh gurus respected the nature and were ‘keshadhari’ and so were their Sikhs. GURU GOBIND SINGHJI MADE THE ‘REHAT’ FROM GURU NANAK’S PRINCIPLES.
The 'bea-adabi of ‘keshas' is the 'ghor apmaan of our great gurus'. The punishment of such type of deed is written in gurbani as
'sant kea dukhan trigad jon kirmaye' (Sukhmani Sahib)-5th Guru Nanak, Ang 279 Sri Guru Granth Sahib Ji
Sikh who cuts his hairs is called ‘patit sikh’. The 'patit sikh' even CAN NOT get birth as human being, but will get birth in the bad and lowest 'yonis'.
Many things does not change, God (nature) has grown hairs on the human body and still human babies beings born with hairs on their body and when they grown up, more hairs are grown on their body as beard and moustache. Our sikh gurus tried to directly connect us to the God and His nature.
‘Pooja Akal ki’ -Guru Gobind Singh
‘Khalsa Akal Purukh ki fauj’ -Guru Gobind Singh
‘balihari kudrat vasiya,
tera ant na jayi lakhiya’-Guru Nanak, Ang 463 Sri Guru Granth Sahib Ji ‘duyi kudrat saajiea kar aasan ditho chaoo’ -Guru Nanak, Ang 463 Sri Guru Granth Sahib Ji
‘sachchi teri kudrat sachhea paatshah’ -Guru Nanak, Ang 463 Sri Guru Granth Sahib Ji
Sikh religion is a way of life. Keeping hairs is a natural God gift. Starting from our 1st Guru Nanak, he emphasis on love for nature. He says that nature is the form of God ("Balihari kudrat vasia, tera ant na jayi lakhia"). So going against nature is not good. When one cuts his hairs, hairs comes again and again. It shows that God's strong desire that man should be with hairs. Guru Nanak also preached that human should obey the orders of God and should be happy and satisfied always with the God's will. That is the very reason that sikh people do not cut their hairs. Other sikh Gurus also followed Guru Nanak's path. Guru Nanak honored this God's will in sikh religion, but every human when loves God deeply, he is developing the habit of not to cut his hairs and give honor to God almighty.
So, it is fundamental rule for Sikhs not to cut their hairs.
Today’s science is also saying that hairs are beneficial to human.
We (Sikhs) all are the sons and daughters of Great Guru Gobind Singh ji, we should accept the sikh traditions with courage and happiness as the children of lion and not to cut our hairs.
