《薄伽梵歌》是印度教的聖典，它不但體大思精、教義深宏，而且還是印度各大古典哲學千流競壑之後的閎大匯聚。其不可窮竭的涵攝力，以及所述及的宇宙法則與不執解脫的光芒，深符印度人的心性之所好。本文藉著維韋卡南達的瑜伽哲學視角，一探《薄伽梵歌》中所蘊含的行動瑜伽（Karma-yoga，羯磨瑜伽）之精義，並且深入分析了「無動機的行動」與「不執」之密義，及其所具備臻至終極解脫的奇妙效果。

Bhagavad Gita is a famous Hindu scripture. It is not only a doctrine with broad conception and meticulous details, but also the convergence of major classics in the philosophy of India in thousands of years. Its perturbation power can not be exhausted, as well as the light of universal laws and Mukta from Non-attachment, which fit the Indian’s minds in depth. This paper, from the perspective of the yoga philosophy of Vivekananda, attempts to explore the essence of Karma-yoga in Bhagavad Gita, and to make a thorough analysis of the “no motivation action” and the secret meaning of “Nonattachment.” Furthermore, it also tries to examine the ultimate liberation of the wonderful results.
