“Those who possess this wisdom have equal regard for all. They see the same Self in a spiritual aspirant and an outcaste, in an elephant, a cow, and a dog.” Bhagavad Gita, Chapter 5
The Bhagavad Gita is dated to the second half of the first millennium BCE. At that time there was not such thing as vaccines. So here I want to add that we can also add into our devotion, to have equal regard for the vaccinated and the unvaccinated. Please see those who are blaming the unvaccinated for what they are, they are not virtuous people, they are people who are satisfied that creating divisions among people is a good thing to do. It is not good to support these people.
A way to show that you have equal regard for all is to oppose vaccine passports. You can do that by writing letters, speaking with people about your realization that supporting vaccine passports is not virtuous, attending protests, and also many other ways.
