Here are 10 TED Talks that will change the way you think forever:

Remember: Just because an idea is old doesn't mean it's good.

Knowing whether old ideas are more likely to be good requires understanding whether conditions have changed in important ways.

Horse archery was an amazing method of warfare for over a thousand years...then people invented guns, and suddenly this great idea that had stood the test of time became obsolete.

Then again, when underlying conditions don't change much, tried-and-true approaches are probably better.

"Learning the lessons of history" usually just means assuming ergodicity and stationarity in an informal time-series model...

Did you know?
Ahilyabai Holkar was one of India's
greatest women rulers of all time.

Ahilyabai was Born on May 31,1725 in the village of Chondi,Jamkhed distt,Maharashtra to a man named Mankoji Shinde,who was the Patil(Chief) of a village and a member of proud Dhangar Community.

Despite the fact that girls' education was a farther dream in those days, Ahilyabai was homeschooled by her father.
Ahilya didn't belong to any royal family but in a twist of fate she is still remembered as one of the most revered Queen in the history.

While they were living their humdrum lives, one day Malhar Rao Holkar, commander of the Peshwa Bajirao & Lord of the Malwa stopped in Chondi on his way to Pune, where he couldn't help but notice a young 8yrs old Ahilyabai in the temple service feeding the poor & hungry.

He was so impressed by the sheer innocence&beauty with simplicity character of Ahilyabai dat he asked her hand in marriage for his son Khanderao Holkar.Just like that she got married to Khanderao in 1733 at a tender age of 8&became a bride of esteemed Maratha community of Holkars

But destiny had something else in store for her as her husband died in the Battle of Kumbher in 1754 leaving her widow at 29.Distressed Ahilyabai was to commit Sati when her father-in-law Malhar Rao refused to let it happen.

SHAKTA DHARMA AND THEIR ACHARYAS

Śhākta or Shakti or Devi pooja is not a new upasana. It is being carried out right from the time of Vedic period. Puran's tell us that Rishi Vashishth would worship Tara devi. Parshuram ji worshipped Tripura devi,

Agastya learned the secrets of Shri Vidya from Vishnu ji in Hayagriva avtaar. Bhagwan Ram, Laxman and Krishna too learned the tantrik vidya. Even Rig Ved 7.103.5 Sayan Bhasya also mentions about Śhākta/शाक्त(शाक्तस्येव शक्तिमतः).

Then we find that in the Harrappan excavations many figurines depicting Shakti were found. So in that age too, which was supposedly an urban city shakti was being worshipped. So naturally this tradition would be prevalent in rural areas too.

It is wrong to say that shakti puja originated from Bengal although it was popular there. Matsyendranath received this vidya from Maheshwari herself in Kamrup. We know that Shakti pooja is practised all over India.

Not much is known about the Śhākta saints in other parts of India in the middle ages.

Adi Shankaracharya wrote Pramanech saar named book on tantra and Anand lahri book on Devi strotras. Then there were Acharya Shankar, Bhaskar Rai, Laxman, Deshikendra, Raghav Bhatt, Krishnand,
