Indriyanam hi caratam yan mano nuvidhiyate
tad asya harati prajnam vayur navam ivambhasi (Text 67)
Tasmad yasya maha baho nigrhitani sarvasah
indriyanindriyarthebhyas tasya prajna pratisthita (Text 68)
Meaning: As a strong wind sweeps away a boat on the water, even one of the roaming senses on which the mind focuses can carry away a man’s intelligence.
Therefore, O mighty armed, one whose senses are restrained from their objects is certainly of steady intelligence.
