Can someone provide online resources to learn Vipassana and Metta? Anything like a PDF or a website link or a podcast audio is OK for me :)
Here I am listing some useful resources for an introduction to Vipassana as taught by S. N. Goenka in the tradition of Sayagyi U Ba Khin:


An Introduction to Vipassana
S. N. Goenka's Inspiring Speech at United Nations
Eilona Ariel's (A documentary filmmaker and Vipassana meditator) TedX Talk
Doing Time, Doing Vipassana - a documentary on use of Vipassana in Tihar Jail
Dhamma.org - link for 10 day course registration at one of many centres in the world 
Introduction to the technique of Vipassana and Code of Discipline for the meditation courses
