According to Advaitic/Yogic sages, all sins and atrocities which are committed by individuals and nations against each other are due to ignorance of the true nature of oneness of all life.
When we view “others” as separate from us and different, we are able to justify all types of ignoble acts against them. Sometimes, even the most heinous deeds are justified in the name of God, religion, or law.
People who are blinded by fear, greed, and ignorance are not able to see outside the cycle of violence that they are part of.
Fortunately, in the history of the world, there have always been good people as well and such noble souls still walk the earth today. I feel that due to their kindness, love, and compassionate influence, there is always a ray of sunshine and a hope to make this world a better place.
The Sage of Arunachala, Bhagavan Sri Ramana Maharshi, gave us the purest teachings.
If we look at the devotees of Sri Ramana, we see that they were some of the greatest yogis and jnanis of their day. But they led quiet, unpretentious, and humble lives fully content in the grace of Bhagavan.
The message of Sri Ramana is to turn the mind within to see our true nature; and then we will see everything to be full of spirit.
In his life, Bhagavan exemplified his realization and manifested immense compassion for all beings. Bhagavan related to plants, trees, birds, animals, and people as sacred and treated everyone who came within his orbit with the utmost respect and love.
Indeed, Bhagavan was most reluctant to accept invitations to criticize others on their spiritual path, even if it was different than the one he advocated. On more than one occasion, Bhagavan told devotees that they should mind their own business and keep in mind what their original purpose was in coming to Bhagavan.
