It is extremely significant that the earliest records, in which we find statements of the awakened thought of ancient humanity, speak of five greatest ideals for which humanity has constantly aspired for throughout its long historical pilgrimage, namely, God, Light, Freedom, Bliss and Immortality. But even more significant is the fact that these earliest records, namely the texts of the Vedas, present to us a systematic account of the methods that were developed in ancient times by which these five great ideals were sought to be realised, even though the language of these texts is symbolic and needs to be interpreted meticulously by the contemporary humanity.
