One should always be cautious, so that no sin happens, so that one has no regrets at the time of death.
Concentration on the unmanifest is not possible.
Keep your luggage packed. (Symbolically this means let not death find you unprepared.)
When the mind realizes God, it is permanently established there and does not desire other things.
Learn to make full use of the human body. One should not waste this chance.
Swami Brahmananda Saraswati (1871-1953)
