佛家語: 因緣而生,随緣而滅。緣聚惜緣,緣散隨緣。So, feel it comfortable to understand this for spiritual healing. While there ia a will, there is a way. Try to help him to look the outside world positively and his past experience is not necessary due to this act. Ask him to do something to help others and share the happiness with them is better than looking backward for the past. Work for today and look and hope for tomorrow !!
