Undoubtedly. His legendary work, the Samarangana Sutradhara has no parallel for its time. In this particular chapter in the Samarangana called Yantra-vidhanam, he describes the method of building pretty advanced mechanical devices like Golakabhramana, Jalayantra & many other.
Bhoja talks about a number of advanced mechanical devices which he calls as "Yantras"

He defines a Yantra as " The device by which the mahabhutas like earth,water,fire,air & ether are controlled. When the free & natural activities of these mahabhutas...cont...
..,the primary elements are made to act in a particular manner by means of some device, it is an Yantra"

Bhoja also classifies these Yantra into 2 types.

1) Svayamvahakam (Automatic devices)
2) Sakrt Preryam (Device that requires occasional propelling)
Some of the Yantras described by Bhoja in the Samarangana Sutradhara. From the simple ones that are seen in children's toys like Ratha dola to super advanced warfare machines.
Bhoja also describes what the characteristics of what can be called a good Yantra. Some of the terminologies used by him to describe good mechanical devices

Shlakshnata - Firmness of appearance
Nirvahanam - Functional efficiency
Laghutvam - Lightness
Shabdaheenatha - Noiseless
Ashaitilyam - Freedom from looseness
Aghadhata - Freedom from stiffness
Vahaneeshu samastaasu soushlistya - smooth & unhampered motion
Dardyam - Durability
Asrunata - Softness
Chirakaalasahatvam - Endurance.

A THREAD on the principles of Hindu iconography & iconometry. In order to fully be able to appreciate our ancient art,one must have a rudimentary knowledge of the various terminologies & methodologies employed by ancient artisans & builders. We'll dwell on that in this thread (1) Image
Before we proceed any further, I'd like you to have a look at the below THREAD on the ancient Hindu system of measurement. A lot of terminologies from there will be used here too. Get yourself acquainted with the different units of Hindu measurement (2)

The ancient Temple builders i.e. the Sthapatis, have consulted various Shastras in order to execute all their wondrous workmanship. The Shastras are many, yet there is much commonality than differences in them. (3)

The Hindu disease of one sided tolerance towards turushka danavas is nothing new. Great freedom fighter & founder of Bharatiya vidhya bhavan KM Munshi writes in the foreword of the book titled " The struggle for empire" which details the turushka invasion of Bharat in detail (1)
He writes "Indian kings, steeped in their tradition of tolerance, could
scarcely envisage the danger to which their policies towards Isl@m
exposed them. In spite of what was happening in North India, Indian
kings permitted foreigners to settle freely in their kingdoms..cont.. (2)
... and granted them free exercise of their religious practices. Even before
the Turkic invasion, some sects of isl@m had drifted into the country
and their religious and proselytising activities had not been interfered with...cont... (3)

Siyar al-Aqtab on chisthi.

"Although at that time there were very many temples of idols around the lake, when the Khwaja saw them, he said: If God and His Prophet so will, it will not be long before I raze to the ground these idol temples... (1)
... It is said that among those temples there was one temple to reverence which the Raja & all the infidels used to come. When khwaja settled there, every day his servants bought a cow, brought it there & slaughtered it & ate it... (2)
P.M. Currie, the author of the book "The Shrine and Cult of Muʻīn Al-Dīn Chishtī of Ajmer" notes:

There is evidence, more reliable than the tradition recorded in the Siyar al-Aqtab, to suggest that this was the case in Ajmer. Sculpted stones, apparently from a Hindu temple..(3)

A piece of advice for all Hindu men. Get into the culture of strength training. If you are thin & skinny, look at ways to add more mass. If you are overweight & obese, burn that fat away. In both cases the best way to achieve this is by adding muscle mass via weight training.
Weight training when complimented by rudimentary training in some kind martial arts will go a long way in self improvement. You'll find yourself to be a lot stronger, agile with good reflexes & reaction times. Focus on compound & explosive movements to build that power & speed.
Of course all this isn't going to turn you into some action hero figure where you'll be able to beat the crap out of a dozen people at a time.

But what it'll give you is a lot of self confidence. Tonnes of it. Will leave you with a fighting chance in tricky real life situations.

Along with Vasudhaiva Kutumbakam, most abused & overused Sanskrit verse is:

"Ekam sad viprah bahudha vadanti"

Sitaram Goel in his book "Defense of Hindu Society" explores the psyche of "Hindus" using this verse out of context & the immense harm they have brought on themselves
Sitaram Goel dwells deep into what makes Hindus, especially leaders from the sangh often quote such Sanskrit verses. He lists two reasons

1) Psychology of surrender
2) Psychology of imitation.

He also give a road map to snap out of this situation.
Regarding the verse itself, it is from the Rigveda 1.164.46.

The full mantra reads as:

Indram mitram varunam agnim ahuh,
atho divyah sa suparNo garutman, ekam sad viprah bahudha vadanti,
agnim yamam matarivãnam ahuh.

Description of the geography of Bharatavarsha in the Markandeya Puranam

Read on 🕉️ twitter.com/i/events/13054…
A Hindu dharmika's reverence for Bharat and everything within its realm is embedded in our genes. We worship its holy kshetras, holy mountains, holy rivers, its holy plants & animals as mentioned in our Dharmashastras.
Everytime we Hindus take a sankalpa during any homa/puja, we invoke the names of many geographical entities within the realms of Bharat. From the lofty snow clad mountains of the Himalayas to the lush green forests of the Dandakaaranya to the plains of the Ramasethu.
