Wikipedia’s definition of a veganism reads:

“ Veganism is the practice of abstaining from the use of animal products, particularly in diet, and an associated philosophy that rejects the commodity status of animals.”

Personally, I utilize the following as a guideline:

“A vegan is a person who’s food choices and other behaviors are directed by a dedication to the commitment to live as healthily and happily as possible while causing the least suffering to the other beings with whom they share the earth”.

Such behaviors naturally include avoiding the consumption of animal-sourced products.

The Vegan Society in 1951 defined veganism as "the doctrine that man should live without exploiting animals". In my opinion, the animus behind enjoying a vegan lifestyle can extend well beyond the confines of not exploiting animals and into behaviors that affirmatively offer kindness, well-being, and peace to all beings. Doing so in fact means consciously choosing products that leave as many people, animals, insects, water creatures, and plants free to live out their respective lives as possible. Beyond that it can include living happily, extending kind thoughts to the world and acting, when ever possible, in an encouraging, nurturing manner.

All of that being said, it is important to me to remember that I can not draw a breath without negatively impacting some other being. The simple act of stepping from my stoop results in a chain of effects that impacts countless other beings in a manner likely not of their choosing. Knowing that results in a humility that lessens my desire to judge others and their actions, and supports my desire to treat others kindly.

To me, enjoying a vegan lifestyle is not only about being conscious about all the other products that use animals such as lipstick, jet fuel, leather, etc., but includes expanding that to practicing a sincere attitude of loving kindness to the widest degree possible.
