有法不拘於法，無法能自為法。

有法不拘於法，無法能自為法。畫在於有生命，生命有大有小，大生命是莊子那種與萬物感通的「物化」，化一己生命為自然萬物的生命，一如余老師把彩鷸、野鳥、生態、自然、人性和人生融在生命中，經由繪畫重現，便成有大生命的藝術，是謂大藝術。余老師在自畫像題詩中有：
「願下輩子化為一隻鳥
飛出生命的自由與美麗」
可以作為我所理解余老師追求生命與藝術價值的註解。

有法不拘於法，無法能自為法。.Paintings starts from life，big or small.Big life refers to the 〝object〞of communicating with all beings mentioned by Zhuang-Zhi(莊子)，the life evolving into all natural beings.It is similar to Master Yu who integrates painted snipes，wild birds，ecology，nature，humanity and living into his life and represents them through paintings similar to arts of big life.Master Yu titled in his self-portrait：〝 I wish to be a bird in next life that flies with freedom and beauty of life. 〞It is the interpretation of Master Yu in pursuit of life and art values.
