Vedas have only produced King Harishchandra, Dashrath, Janak, Abhimanyu, Arjun, Yudhishtr and several others the warriors and justice and Vyas Muni, Kapil Muni, Guru Vashishth, Atri Rishi, Agastya Rishi and other several the knowledgest and Mata Sita, Ansuya, Savitri and several others and Bal Brahamcharini Gargi, the guru of king Janak.But due to our bad luck that we have forgotten Vedas and therefore rebirth of the said dignities are not being made visible, though the worship is lot in India.So a complete guru is he who knows four Vedas and ashtang yoga and complete knowledge of karma, upasana and gyan.In this connection Yog Shashtra sutra 1/26 also says that first guru is God and we must follow his knowledge of Vedas through present guru.
So please be careful to find a real guru and beware of false prophets. I was among the competent students but for last two years I am facing absent mindedness, lack of concentration, laziness and tiredness of mentality. A student is to concentrate only n study and health, being his moral duty.Swami Ramswarup: Bhim had Ghtothkach from Hidimba, the only son. But this is history and we must remember it to make alive the culture to maintain the only good task in present life.Otherwise we must always recite and remember the holy name of God for getting peace. What do one need to know when seeking a living Guru? The eternal culture of the universe are four Vedas the knowledge of which is generated in the heart of four Rishis by God himself.However, to chant the mantra mentally is more powerful and you may chant mentally even while walking or in lying position.I have explained meaning of gayatri mantra on the web site.
