The Great Indian Sages..

Rishi Kanada(कणाद) (?BC-?BC)

Rishi Kanada is one of the most profound physicists in entire human history.

The century in which Kanada lived, as per the western scholars, is inexact just like how Mahabharat & other historical events are ill-timed.
In his work Vaisesika Sutra, he talks about various concepts of physics such as types of substance, their attributes, and actions, atoms, the eternality of atoms, the nature of mind, consciousness, space and time, the concept of invariance, the list is long.
Vaisesika Sutra is a treasure for both philosophers and physicists.

Some of the highlights from his work (this list is too small compared to the treasure of knowledge in his actual work):

- He talks about a system that includes space, time, matter, as well as observers.
- He talks about aṇu, the most fundamental particle.

- He defines four types of atoms, two with mass (similar to proton & electron) & two with little mass (like the modern neutrino & photon)

- He talks about the concept of invariance.
- Rishi kanada anticipated the laws of motion, yes, you read that right! As follows:

>>> In the absence of conjunction, gravity [causes objects to] fall

>>>In the absence of a force, there is no upward motion, sideward motion, or motion in general
>>>The initial pressure leads to the arrow’s motion; from that motion is momentum, from which is the motion that follows and the next and so on similarly

>>>Action(karya) is opposed by reaction(karman)

The above principles are effectively equivalent to Newton’s laws of motions
For a detailed and technical understanding of Rishi Kanada's work in Physics, please read this brilliant article by @subhash_kak sir

Rishi Kanada is not just a scientist but an enlightened being

Interestingly, all ancient Indian scientists had always considered science & spirituality as two sides of the same coin & thus their work binds science & philosophy so beautifully & accurately.

Sheer brilliance!🙏

Many people wonder why Hinduism has so many sacred books? And which really is the main book of Hinduism?

There seems to be a lot of confusion around Hindu scriptures and below is a humble attempt to throw some light on some of the primary Hindu scriptures.

1/n
Santan is a pluralistic religion & allows people to express fondness for God in their own way.

Thus, there is huge literature available on Hinduism, encompassing thousands of books.

However, the primary & authoritative text of Hinduism is only The Vedas, the ‘Shruti’.

2/n
All other literature is considered ‘Smriti’ and consists of commentary, explanation, deeper philosophy on the teachings of the Vedas.

Now the question is what is 'Shruti' and what is 'Smriti'?

The Sacred Hawan Or Yagna..

What is Hawan or Yagna and why is it performed?

Yagna literally means "worship, sacrifice or offering”. It is a process of invoking a sacred fire with the intention of cleansing one’s material and spiritual body, and the environment. Image
The process of Yagna is described as the most important Karma in the Karmakand of Vēdas

"अयं यज्ञोः विश्वस्य भुवनस्य नाभिः"

In Yajurveda, Hawan is said to be the Naabhi (nucleus) of the entire world. Nabhi has an important place in Human body, so is the role of Yagya in world.
In Yagna’s four types of materials are put in the fire:

1. Scented materials such as Kasturi, Saffron, etc.
2. Sweet materials such as jaggery, Honey, etc.
3. Strengthing materials such as Ghee, Milk, Rice, etc.
4. Health preserving materials such as Herbs.

The Great Indian Sages..

Pippalada was an ancient Indian Vedic sage, philosopher, and a teacher of the Atharvaveda. He established his own school of Atharvaveda known as the "Pippalada-sakha".

Pippalada is the master of the Prasna Upanishad, one among the ten Mukhya Upanishads
Upanishads are one of the primary Hindu texts.

The word ‘Upnishda’ has been derived from the root Sad (to sit), Upa (nearness) and Ni (totality). Thus, this word means ‘sitting near by devotedly’
Coming to Prashna Upanishad which contains six Prashna (questions), and discussion on their respective answers.

The 6 questions are the deepest questions of life and remain as vital as thousands of years ago.

The Great Indian Sages...

Maharshi Patanjali (??) - Known as the father of modern yoga, Patanjali did not really invent yoga. Yoga was already there in various forms.

Maharshi Patanjali assimilated all aspects of Yoga together and gave the world the very famous 'Yoga Sutras'
The history of Yoga can be traced from Vedic scripture to the modern period, throughout which it underwent successive refinements.

However, Yoga as a discipline was detailed first by Patanjali in his Yoga Sutras, the first systematized treatise on Yogic theory and practice.
Contrary to the modern understanding of Yoga as a form of physical exercise, the Vedic/Hindu concept of yoga is much deeper involving mind, body, and soul.

In a similar line, in the yoga sutra Patanjali talks about not just the practice of yoga but about life and beyond.
