In plain words
In the end he forgot his very body. An anthill grew up over that body. From the anthill he was uttering Rāma's Name, "Rām, Rām". Along with Ahaṅkāra he forgot attachment to the body as well. Attachment to the body, pride in learning, pride of caste, pride in wealth: all such attachments bind man. The day he let go of all these, that very day he was transformed into a maharṣi. Not merely a maharṣi. He earned the right to be the maharṣi who would write the story of Śrī Rāmacandra. It was the sight, the touch and the conversation of the elders that made Vālmīki, who lived in tamoguṇa, so great. By their company all his evil qualities became holy. Viśvāmitra too was the same. At first he was the great king Kauśika. The great king was rājasic. Such a man renounced, gave up his kingdom, put comfort and peace out of his mind and practised tapas. In the end, by Vaśiṣṭha's teaching, he was transformed into a maharṣi. He turned into a brahmarṣi. From rājarṣi he became brahmarṣi.
What is the sāttvika? Constant calm, patience, sympathy, Satya: all such things are sāttvic qualities. He gives not the least room to lust, anger, greed, pride and envy. Whatever hatred comes, it turns it into Prema.
A small example. None of you should think anything of it. Swami is constantly spreading the principle of Prema. In every discourse He utters "Prema, Prema"; how many of you experience this Prema? How many practise it? If someone comes and asks a question, one does not see a single person who answers with Prema. In the Mandir, or the canteen, or the bookstall, or the accommodation, or the hospital: wherever you go, there is no such word as Prema. Why should you listen to discourses? Is even one person to be seen who answers with Prema? When some newcomer comes and asks when Swami's darśan time is: Don't know, go, go. Could they not say what they know gently and calmly? Then if you ask the educated, they say, "this is not my duty go". Is a duty needed for this? What is lost in answering gently, with Prema, what is asked? Among the women and among the men alike, they have lived in the ashram twenty years, thirty years. Not even one of them has a heart full of Prema. They go on doing sādhanas. They go on doing japa and tapas. For what? What has become of this Prema in them? They are killing Prema, these people.
