When meditation is mastered, the mind is unwavering like the flame of a lamp in a windless place. – 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
That one I love who is incapable of ill will, and returns love for hatred. Living beyond the reach of I and mind, and of pain and pleasure, full of mercy, contented, self-controlled, with all his heart and all his mind given to Me — with such a one I am in love. – Bhagavad Gita
