In plain words
Viśvāmitra discovered the Gāyatrī mantra. This is connected to the power of the sun. It is exceedingly powerful; it is a great mantra. There is an utterly wondrous power in it. It is well known to readers of the Rāmāyaṇa that Agastya, through the teaching called the Āditya-hṛdayam, explained the secrets of solar power to Rāma in the Rāmāyaṇa. Reciting that mantra and believing in it with devotion and faith, Viśvāmitra obtained unprecedented weapons and became greatly accomplished. Viśvāmitra was the great scientist who, through this power, created a counter-creation to creation. A 'scientist' is not merely one who discovers wondrous power with physical apparatus. It is precisely such a person — one who, taking spiritual power as his basis, becomes a seer of mantras, performs spiritual disciplines, and, with faith and devotion and constant practice, brings this power into constant experience — whom they formerly called a 'scientist.' However, today's scientists, having read and learned some little bit, and having made it out to be more than it is, are, with ostentation, soaring to the skies with arrogance, saying 'we have obtained utterly wondrous power.'
Such ostentation is an act contrary to a person of true wisdom. It was Viśvāmitra who, being humble and obedient, thought that there were still, still ever so many more things that could yet be known, and that all these are possible only through divine power, through grace. There is no other scientist greater than him. But it is regrettable that Bharatiyas, even though this Viśvāmitra — such a distinguished, accomplished, broad-hearted person — was Bharatiya, do not recall such a great ṛṣi, and instead trust and keep describing the deeds of foreigners who have recognized only some atom's worth of what Viśvāmitra discovered. While it is foreigners themselves who are coming to know the Bharatiya Vedic texts, having researched them in various ways, Bharatiyas themselves do not trust the Veda-mother, who is the mother of Bharatiyas, and love a foster mother affectionately instead — this itself may be thought to be the fruit of infatuation with an English education.
