Then, when you retire at night, sit up and examine quickly all the experience of the day. See whether you have caused pain or displeasure to any one by any word or deed. Then pray, "I am now dying and falling into Your lap. Pardon me for any lapse; take me under Your loving shelter." After all, sleep is a short death and death is a long sleep.
(From : Sai Veda, The Word of God, sayings of Bhagavan Sri Sathya Sai Baba)
