In plain words
like the life-breath. In the Vedas there is also a wondrous divine power. A wisdom-filled mantric power, too, lies embedded within. Along with tantric power, there is also a sacred divine power. That which accomplishes its task by using this great power is precisely tantra-śakti; this alone is called 'tantram.' Using mantra and tantra, the ancient Bharatiya great ṛṣis embedded, in the four sacred Vedas, the machines that human physical-scientific power drives, and the whole apparatus of ritual.
Unable to grasp these truths, many people think, the moment 'Vedas' is said, that these are meaningless, useless mantras recited by orthodox conservatives. Not only the moderns — even elders who have gained the name of eminent scholars, propagating the Vedas with knowledge of their meaning, also put them to use for their own self-interest, being unable to recognize their sacredness, and, using them only according to convenience, are unable to put them into practice. For that very reason, moderns are unable to believe in the Vedas. The very best of scholars, well-versed in the Veda, not putting them into practice, not having complete faith, and not telling their own children about them — this very thing is the reason for disbelief. There are also some others who, whether they understand it or not, recite with errors, walking about the market, in an orthodox, rote manner. In Bharat, especially German scientists, even though they did not recite these mantras, discovered well, and recognized, the great power within the mantras. They carried off certain portions of the Vedas, and, with special patience, conducted many kinds of research, observed, and discovered wondrous matters. They proved that all the accounts necessary for human progress are found in the Vedas. From the Vedas alone the upa-vedas emerged. Dhanurveda, Āyurveda, Jyotirveda and however many such — there are ever so many.
