How did the knowledge of great weapons like Bramhastra got lost in Hinduism tradition? As can be seen in Ramayan and Mahabharat, Gurus used to give knowledge of weapons to their shishya which were then used to protect Dharma. But eventually this knowledge was lost and Bharat couldn't fight invaders. How did this happen? Why weren't Devas invoked through yajnas when Sanatan Dharma followers were ethnically cleansed at the rate of millions by foreign invaders? At time of Mahabharat Indra himself helped Arjuna by granting him weapons. What happened now?

  • I have read 1000's of books including vedas,puranas,upanishad,tantras,maths and scientific ones and what i understand is that the entire existence is complete 0 which is the universal egg.And when spreaded lead to - and + values which when summed up has total value of 0.So to maintain the 0 their should always be - values too along with the + one's.So their can't be always fruits their must always be bad too.This four yuga cycle ensures that.Everything is karma – Pravin RGMishra Mar 10 at 7:58

    What makes you think all those shastras are real in the first place? Once you realize they are all mythological weapons, the question How did the knowledge of those "weapons" got lost? doesn't even arise. – sv. Mar 11 at 18:18

    @sv I cannot see the past but I used shabda praman to reach that conclusion. – Lokesh Mar 12 at 4:18

    @sv Yes, I trust the series of events mentioned in our itihas (history). – Lokesh Mar 13 at 1:32

Normally, a competent Guru is required to understand a subject at deeper levels. It applies to every branch of knowledge, be it SPIRITUALITY, or science or arts or something else.

Again, a competent Guru will not share all his knowledge to every passerby. He/She should find a suitable disciple, who is competent enough to receive the knowledge.

Sri Ramakrishna Paramahamsa used cry for worthy disciple, while Narendranath (Swami Vivekananda) was searching for a worthy Guru.


It happens in every branch of science. If one finds the divine weapons mentioned in the Epics like Ramayana or Puranas, but unable to find them in the present age, that situation can indicate innumerable reasons.

For example Sage Viswamitra did not impart his knowledge in divine weapons for every king of his times. He waited for long for the birth of Sri Rama.

A worthy Guru waits for a worthy disciple. That is the underlying principle.

Drona did not impart all his knowledge in archery to every one. He imparted that knowledge to the Arjuna only. Out of love towards his son Aswathama, he taught the latter the knowledge in Brahmasirsha, which is all powerful, which proved to be detrimental to the mankind.

Competency of disciple includes his/her balance of mind in utilising the knowledge that acquired and searching for a worthy disciple in turn for passing on the knowledge.

With the elimination of most of the kings in Mahabharata, the society degraded and humans lost the ability to acquire and retain knowledge of great things.

That was how we lost touch with the pure SPIRITUAL concepts of Vedas and got degraded into ritualistic society.

Similar was the case with other branches of knowledge, knowledge of divine weapons being one among them.

  • Lot of speculation here. Please add references for these statements: "With the elimination of most of the kings in Mahabharata, the society degraded and humans lost the ability to acquire and retain knowledge of great things." (besides, things like moon landing, nuclear weapons, internet, AI, etc. do not support this line of thinking). – sv. Aug 28 at 16:45
  • There is a difference between interpretation and speculation. Earlier in the case of Vedas also I stated Vedas contains spiritual aspects for which you didn't agree. It is your choice to accept my interpretation or not. @sv. – srimannarayana k v Aug 28 at 23:46
  • References are needed whether or not I as a reader agree with your views. I just review answers based on what's written in the answer and how well the references used support the statements made. Please don't take my comments personally. – sv. Aug 29 at 0:50
  • I am not taking personally. There was a mention about divine weapons in EPICs, which are not available now. Competence in Guru as well as Disciple is crucial. The knowledge of weapons was lost because there is no competency in subsequent generation. It is my interpretation but not speculation. @sv. – srimannarayana k v Aug 29 at 1:05
