These men were homeless and meditated their way into the hearts of the people.
Many believed in philosophy based on sound principles like love, peace, charity, goodwill, non-violence, equality, freedom and many other universalities.
We all have the choice to embrace such a good practice in which every religion, nation and people have used since the beginning (and all will have the chance to use until the end).
It seems almost conducive to homelessness, meditation and a desire to live a better life.
But there seems to be help for any lifestyle or individual or group.
It is also true that all these leaders suffered terribly by the oppressors of the time.
It seems a good exercise to study these people and to learn their practices and perhaps put them to good use.
