Spiritual meditation is the pathway to Divinity. It is a mystic ladder which reaches from earth to heaven, from error to Truth, from pain to peace.
Meditation has to become your heartbeat; even when you are asleep the meditation continues like an undercurrent.
The disunited mind is far from wise; how can it meditate? How be at peace? When you know no peace, how can you know joy? The Bhagavad Gita
When meditation is mastered, the mind is unwavering, like the flame of a lamp in a windless place. The 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. The Bhagavad Gita
