This prayer reveals to us the way of consecration.
April 4, 1914
O LORD, my adoration rises ardently towards Thee, all my being is like an aspiration, a flame which is consecrated to Thee.
O Lord, Lord, my sweet Master, it is Thou who livest and wiliest in me!
This body is Thy instrument; this will is Thy servant; this intelligence is Thy tool; and the whole is only Thyself.
The text above is quoted from the Third Edition, 1954 (translation by Rishabhchand Samsukha)
