The senses have been conditioned by attraction to the pleasant and aversion to the unpleasant: a man should not be ruled by them; they are obstacles in his path. – Bhagavad Gita
He is not elevated by good fortune or depressed by bad. His mind is established in God, and he is free from delusion. – Bhagavad Gita
Those who eat too much or eat too little, who sleep too much or sleep too little, will not succeed in meditation. But those who are temperate in eating and sleeping, work and recreation, will come to the end of sorrow through meditation. – Bhagavad Gita
When meditation is mastered, the mind is unwavering like the flame of a lamp in a windless place. – Bhagavad Gita
