We are indeed very fortunate to be able to receive the teachings on the Wheel of Sharp Weapons easily and freely on the Internet. In the past, Atisha had to leave India, traveled on the great Indian Ocean and sailed to Indonesia where he met with a different culture, language and so forth.
He found his Guru Dharmarakshita Amazing! He became so devoted and Dharmarakshita just poured the teachings into him like a big receptacle. The challenges and dangers he experience sailing to and back from Indonesia did not deter him from the Dharma. We who are filled with self-made obstacles cower at the first encounter with difficulty.
Anyway, the Wheel of Sharp Weapons is perhaps one of the more accessible and practical teachings that Atisha brought back from Indonesia. It’s relevance today have no parallels. Hence, it is an ideal teaching for everyone – the most advance practitioner as a reminder and meditational tool or the newest of practitioners.
PS: For English speakers, you would be delighted to know that Tsem Rinpoche speaks perfect English.
