"Equality" is the basic principle that every person should learn to appreciate in this life.
It is true that people are different. They have different tastes, different aptitudes, different interests, different ideas and different attitudes; may be even different levels of skill in a particular topic or different talents. Infact, identical twins have been said to be different in some way!
Nevertheless, the basic human principle is that every person in this world deserves equal opportunity to become what they want to be.
When more people understand this simple truth; love will abound more in this world. Life will be sweet as humans will realize they are all part of the same global family (vasudhaiva kuTumbhakam)!
Love is the only religion we ever needed and will always need!
