For determining the criteria for a right life, it is necessary to first correctly define ideals of humanity and basic universal values, from which any ethical concept should push off.

Gazing a thousand years into the future, through the prism of the Universe, what do we see? Does humanity still exist? What's the state of life? What would we like to witness? So, which values are most important today?

Love — the fundamental basis of a fulfilling life. It is a feeling of deep sympathy, aspiration and affection. Nascent and developing through personal growth and awareness of important values, it is expressed through responsibility, respect, kindness, and creativity, the fruits of which bring happiness and multiply the love.
