«Love your neighbour as yourself»

To support peace on earth,

e-mails sent by OPAL include this Great Commandment,

this core message of Christianity, which is found

in all the established religions of the world.

This, as a small reminder and motivator

at a time in which egoism, greed

and hostilities did increase

significantly in global

world politics.

Please see for example Christian references (Matthew 5:9, 5:44-46, 19:19 and 22:37-39, Mark 12:28-34, Luke 6:27-28 and 10:27, Romans 13:9, Corinthians 13:2 and 13:12-13, Galatians 5:14, James 2:8), Jewish references (Leviticus 19:17-18, Leviticus 19:33-34, Talmud, Shabbat 31a, Tobit 4:15), Islamic references (Number 13 of Imam “Al-Nawawi’s Forty Hadiths”), Hinduism references (Mahabharata 5,1517 and Mahabharata, Anusasana Parva 113.8) and Buddhism references (Samyutta NIkaya v. 353 and Udana-Varga 5:18) as mentioned for example here (pdf), here or here. «Love your neighbour as yourself» is also the basis for humanity, living together and peace in our world, especially in times of climate changes and depletion of resources. Thank you for supporting this message.

Love, compassion and forgiveness was shown and explained at the
National Remembrance Service for the victims of the Christchurch mosque attacks
from 15 March 2019 (TVNZ 29.3.2019).

Thank you.

Reflections on Corona and Easter – Taking Care of Paradise

OPAL experience report:

International Project Aid

As an organization that is active in development cooperation and must maintain contact with many beneficiaries, contributors and donors, since 2001 OPAL is for us a reliable help everyday.

We not only send individual e-mails and letters with OPAL, but also do all the mass mailings with OPAL.

OPAL helps us in managing the addresses as well as with the challenge to keep track of the dossiers and all correspondence with all persons and organizations in our environment.

Pietro Tomasini,

Founder and managing director

International Project Aid

OPAL experience report:

sahee foundation

The sahee foundation has been working with OPAL since 2013 to manage our data. As a decentralized working team the program (OPAL) has become an indispensable tool for us.

Thanks to OPAL, correspondence and agreements with project partners can easily be understood and supervised (Dossiers), addresses can be managed and used in a simple manner.

In particular, we also value the extremely service-oriented work by the OPAL developer Wolfgang Rehfus, who always assists us in case of questions or problems.

We can highly recommend OPAL as a database for addresses and dossiers, especially thanks to the service, which goes far beyond our expectations.

Cyril Alther & Gabriela Landolt, sahee foundation
