Man falls from the pursuit of the ideal of plan living and high thinking the moment he wants to multiply his daily wants. Man's happiness really lies in contentment.
It is the activity of the intellect that constitutes complete human happiness - provided it be granted a complete span of life, for nothing that belongs to happiness can be incomplete.
Material objects give rise to physical happiness, while spiritual development gives rise to mental happiness. Since we experience both physical and mental happiness, we need both material and spiritual development. This is why, for our own good and that of society we need to balance material progress with inner development.
Stay, stay at home, my heart and rest; Home-keeping hearts are the happiest, For those that wander they know not where Are full of trouble and full of care; To stay at home is best.
