Sebuah Catatan Dari Alam dan Pengalaman

"....semua makhluk ciptaan Tuhan samada manusia,binatang,tumbuhan, alam semulajadi dan sebagainya,saling perlu memerlukan,saling bantu-membantu kerana mereka berkait,terikat antara satu sama lain dalam satu kitaran yang berhubungan. Justeru, jangan diputuskan ikatan itu, kelak, seluruh kitaran akan musnah..." Ahmad Rais Johari
