KATHOPANISHAD

In the gita Class, couple of weeks ago we discussed about comparing the body to the chariot metaphor and some of the attendees wanted the particular quote. Here it is. I am quoting from the Kathopanishad including the original mantra.

atmanam rathinam viddhi sariram ratham eva tu
buddhim tu sarathim viddhi manah pragraham eva ca
indriyani hayanahur visayamst su gocaran
atmendriyamanoyukam bhoktety ahur manisinah

The meaning is:
Know the self as the occupant of the chariot, the body as the chariot itself; know the intellect (buddhi) to be the charioteer and the mind (manas) as the reins.
The wise ones speak of the senses as the horses, their objects as their turf and they speak of the soul along with its body, senses and the mind, as the enjoyer (bhokta).
The individual is the passenger in the car of the material body, and intelligence is the driver. Mind is the driving instrument, and the senses are the horses. The jeeva(or the individual self) is thus the enjoyer or sufferer in the association of the mind and senses. In the absence of its body, senses, mind and intellect which are metaphorically referred to as chariot, charioteer, horses and reins, there is no agency on the part of the inactive self who is figuratively spoken of as the rider in the chariot in respect of actions, both mundane and scriptural, of the form of movement.
The purpose of the metaphor of chariot etc., in respect of the body is explained in the following two mantras.

Yas tv avijnanvan bhavaty ayuktena manasa sada
Tasyendriyany avasyani dustasva iva saratheh
Yas tv avijnanvan bhavaty yuktena manasa sada
Tasyendriyany avasyani dustasva iva saratheh
The meaning is:
For him, who always remains ignorant with his mind un-concentrated, his senses become uncontrollable just as wild horses for the charioteer; but for him who becomes intelligent always with his mind concentrated, his senses become controllable, just as trained horses for the charioteer, (are controllable).
In this world indeed to the one, who has got a good charioteer and reins, the horses become obedient. In the same manner only when the intellect and mind, metaphorically spoken of as charioteer and bridle are good (trained and disciplined), the senses, as compared to horses, become obedient and not otherwise.
