I have not, I will not have.”

And extinguishes fear in the wise.

Nāgārjuna , is widely considered one of the most important Buddhist philosophers. Along with his disciple Āryadeva, he is considered to be the founder of the Madhyamaka school of Mahāyāna Buddhism. Nāgārjuna is also credited with developing the philosophy of the Prajñāpāramitā sūtras and, in some sources, with having revealed these scriptures in the world, having recovered them from the nāgas . Furthermore, he is traditionally supposed to have written several treatises on rasayana as well as serving a term as the head of Nālandā. Wikipedia
