The archery metaphor from the Mundaka Upanishad describing the teachings of Vedanta as unfolded by Swami Paramarthananda.
The target is Brahman, the one true Self. The arrow is the Jiva (hunan being), a traveler. The archer is the teacher. The practices of karma yoga (the attitude with which action is taken) straighten the arrow, while the tip is sharpened with upasana yoga (disciplining the mind, focusing the energy). The bow itself is jnana yoga (self inquiry), and the process of pulling the string back, is withdrawing the senses and quieting the mind.
May you fly straight and hit the bullseye!
