God does not listen to the language of the tongue which constitutes Japs (mental repetitions), Mantras (verbal repetitions), Zikra (either kind of repetition), and devotional songs. He does not listen to the language of the mind which constitutes meditation, concentration and thoughts about God. He listens only to the language of the heart, which constitutes love.
The most practical way for the common man to express this language of the heart, whilst attending to daily-life duties, is to speak lovingly, think lovingly, and act lovingly towards all mankind, irrespective of caste, creed and position, taking God to be present in each and every one.
-Path of Love, p67
