Paramahansa Yogananda said:
The wise do not expect to reap everlasting happiness from friends, beloved family, or dear possessions! The forms of loved ones are snatched away by death. Material objects turn out to be meaningless when one becomes used to them; or when, in old age, the senses grow unappreciative, powerless. Concentrate on the immortal Spirit through meditation and find there a harvest of eternal, ever new peace!
