Treat all as your own self. Do not have a double standard.
Service is the highest spiritual discipline. Prayer and meditation, or knowledge of scripture and Vedanta (holy scriptures of India), cannot help you reach the goal as quickly as service can. Service has a double effect, it extinguishes the ego and gives bliss.
You must be a Lotus, unfolding its petals when the Sun rises in the sky, unaffected by the slush where it is born or even the water which sustains it!
What you would desire others to do for you, you should do for others. You should respect others, as you want to be respected by them.
Discipline trains you to put up with disappointments, every rose has a thorn.
Always respect another's opinion and another's point of view.
You have it in your power to make your days on Earth a path of flowers, instead of a path of thorns.
Before you speak, think -Is it necessary? Is it true? Is it kind? Will it hurt anyone? Will it improve on the silence?
