In plain words
(Swami Himself sang the bhajan ‘Rāma Rāma Rāma Sītā...’ and led the devotees in singing it, and then, continuing His divine discourse, said:)
Embodiments of Prema! If you speak the Name of God with love even once, your heart will swell with joy; even a hard heart will melt. Even a block of ice takes some time to melt, but when you remember the Name of God with Prema, God's heart melts in a moment. The power of God in you grows in a moment. So go on remembering the Name of God. Even when you are travelling anywhere, remember the Name in your heart without others knowing. ‘Always, at all times, everywhere, the thought of Rāma.’ There is no sādhana greater than this. This is the essence of all sādhanas! So, Embodiments of Prema! Remember the Name. In the Kali age there is nothing greater than remembering the Name.
The Name of Hari, the Name of Hari, the Name of Hari alone; in the Kali age there is no other way, no other way, no other way at all.
