Recognizing that human beings have vastly different psychologies and inclinations, Krishna outlines the different authorized paths to achieve this ultimate realization. Some achieve the vision of the Supersoul (Paramatma) through intense, solitary meditation (dhyānena). Others reach it through deep philosophical analysis and the cultivation of knowledge (sāṅkhyena yogena). Still others arrive at the exact same truth through selfless action and duty (karma-yogena).
