Whether we serve God outwardly in some way, or inwardly in meditation, we still serve Him by offering our thoughts and energy into His river of love. Both are matters of self-giving.
Our work should be a conscious, loving service to the Lord. It should be a devotional offering to Him.
That person alone who understands the path in terms of self-offering can attune himself to God’s grace. For grace, too, is a self-offering, on God’s part, of love. By giving of oneself, the heart’s chalice becomes emptied and cleansed, making it possible thereby for God to fill it.
