Samurai armour was really quite deceptive when it came down to appearance, it looks really fragile and not fit for purpose, but was extremely tough. The Samurai developed a special lacquer which was used to toughen natural materials. This enabled the armour to retain toughness and lightweight properties which enabled the Samurai to move with speed and agility. They wore face masks that were intended to frighten the enemy whilst masking ones own expressions during battle.
Today we have a major issue with Sikh youth walking into university classes like sociology and walking out extremist. Whether that be feminist extremist or LGBTQ extremist or atheist. When it comes to Gurbani these groups and people look for lines or a line of Gurbani and take it out of context to support their extremist LGBTQ beliefs on marriage, gender being same or new thing no gender or infinite gender. Like we had the ignorant couple from the states who got married by having his wife walk along with him. The point being they dont follow Guru Sahib. They attain 'knowledge' else where and want to force it on Sikhi. The Sikh youth laugh at the Sikhs who bow at a fake baba's feet. But, the irony is the Gurmukhs are shaking their head at both of them. One is bowing to a fake baba and the other is bowing their mind by accepting secular knowledge that will always be in the trial phase. Neither are better than the other. The youth of today, and it's been done by a few old farts, attain masters or doctorate in fields like chemistry, sociology or another field and then say we have a doctorate in Sikhi. They write articles on what they want Sikhi to be and in their name they put "dr.". Such deception is being done by these old farts. Sikhi is about honesty, yet they start their article with deception.
If you want to be a Sikh, then Sri Guru Granth Sahib ji is the teacher and classroom. Not your sociology professor who tells you abortion of a 37 week baby is a women birth right choice, but dont kill that cow because imeat industry is killing the environment, go vegan.
In short, dont be the monkey with the wrench.
When it comes to other religious scriptures why did Guru Sahib say to read them? Was it to understand how to be moral? Gurbani provides us with spiritual wisdom and morals of the highest kind. It would be counterproductive to look else where for morals. Guru sahib says, give me your head (completely and only focus on the shabad) when you come on the Gurmat path. Guru Sahib tells sikhs to read other religious scriptures because when a Gurmukh has fully attuned his mind with Gurbani he can see naam everywhere. So when reading other religious scripture the Gurmukh can pick up on the naam that is there and serve the humans that are lost in the vedas, gita, bible, Koran, Torah, etc. Also Gurbani makes references on other religious scriptures concepts so we can achieve a total picture of their concepts when reading their scriptures. But many lose sight of the goal and start collecting merchandise (intellectual knowledge and maya)from these scriptures. But Guru Sahib says all merchandise can be achieved from Gurbani. Anand Sahib says this path is sharper than a double edged sword and finer than a hair. The path of Gurmat can be simple if we follow the instructions of Gurbani or life can be made difficult by losing the purpose in life as Gurbani describes it.
I try to read it once a year. There's a lot to be learned from a human perspective in terms of the morals and the arguments it raises. A person doesn't have to be a Hindophile to glean something meaningful from the text.
