In judging our progress as individuals we tend to concentrate on external factors such as one's social position, influence and popularity, wealth and standard of education... But internal factors may be even more crucial in assessing one's development as a human being. Honesty, sincerity, simplicity, humility, pure generosity, absence of vanity, readiness to serve others - qualities which are within easy reach of every soul - are the foundation of one's spiritual life.

The very right to be human is denied every day to hundreds of millions of people as a result of poverty, the unavailability of basic necessities such as food, jobs, water and shelter, education, health care and a healthy environment.

The more informed you are, the less arrogant and aggressive you are.

Sometimes, I feel like one who is on the sidelines, who has missed life itself.

As the years progress one increasingly realises the importance of friendship and human solidarity. And if a 90-year-old may offer some unsolicited advice on this occasion, it would be that you, irrespective of your age, should place human solidarity, the concern for the other, at the centre of the values by which you live.

Our motto should be: let us make peace so that we can concentrate on the really important work that needs to be done. That is, alleviating the plight of the poor and the defenceless, for as long as most of humanity feels the pain of poverty we all remain prisoners.

You can never have an impact on society if you have not changed yourself.
