This is an old post I saved many years ago in my files, which I found on The Bhaktivedantas website. After re-reading it, I realized why I saved it. It is good information.
Krishna Consciousness in a Nutshell
by Hansadutta das
Krishna consciousness is the original consciousness of every living being, and it is explained in different Vedic literatures. One of these literatures is the Chaitanya-charitamrita. Chaitanya-charitamrita means “characteristic of the eternal living force”. Every living being is eternal by nature, and because he is eternal, he cannot be happy in this material world, which is a temporary arrangement, however wonderful it may be.
…Every living creature is subjected to four basic miseries, beginning with birth, continuing into old age and disease, and ending in death. No one wants to be miserable–everyone wants to be happy–but material nature functions in such a way that no one can be happy.
What is the Hare Krishna Program for Self-Realization?
…This movement is primarily spreading the teachings of Bhagavad-gita and Srimad-Bhagavatam and the chanting of the holy names:
Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare
