From Collectanea by Mary Baker Eddy, pages 34-35 of Addenda
It is unnecessary to go anywhere or change anything to find the glories of God. We need only open our eyes to spiritual reality, to the omnipresence of God, good, which is always available to us.
For every material sacrifice there is a spiritual blessing. Right desire is the deepest form of prayer.
I tell you truth when I say there is only one source of all good — God. The conscious recognition and acceptance of this fact acknowledged by every activity of the mind, not two or three times a day — but every few moments all day long — no matter what the outer self is doing, and this maintained, will enable anyone to express his perfect freedom and dominion over all things human.
Today is my day. And my world is but a reflection of my own mental attitude. I have the power within myself to reverse any destructive thought entering my mental household. I could not lovingly entertain unwelcome visitors, therefore I shall not willingly entertain unwelcome thoughts.
Each day I shall weed from my mind all thoughts of doubt, fear, malice, hatred, revenge, petty criticism or superstition of any nature whatsoever, and shall begin today believing tremendously in the power of a constructive mental attitude.
This is the day that the Lord has made. In it I will rejoice and be glad. No man taketh my joy from me. Just for today I will know that I am God’s child under His protection and that no plague can come nigh my dwelling. Just for today I will know that God is good, and that God is Love, and that He knoweth them that trust Him. Just for today I will know that I have strength to meet and conquer every claim of error, and that under the guidance of divine Principle I will be led to throw open the door for the entrance of Truth, and know through that same door error is cast forth. Then with a sweet sense of God’s nearness, I will know that yesterday has gone, and left no bitterness, and that today is big with blessings, that tomorrow belongs to God; and to realize this today eliminates all worry and pain and trouble, and brings us peace and happiness.
