Prakash: Namaskar swamiji, 1)muslims, christians and others know why they are so and so! why hindus are hindus ?
2) do Vedas declare idea of four yugas? sat, treta, dwaper, and kalyug ?
Swami Ramswarup: Namakar.
(i) learned Hindus also know that why they are called hindus. In this connection, I paste my answer below:-

About Hindus

The word Hindu was used for all the citizens who lived in India across Sindhu River. This word was used for the first time by Greeks and Unanis. Thereafter Arabians and Farsis used this word. So in reality Hindu means all the citizens, whether Sikh, Muslim, Christian or others, of India. Just like in America all type of citizens live there but are called citizens of USA i.e.,Americans.

Nowadays it is called that Vedas, shastras, Geeta, Ramayana and some other holy books of Sanskrit languages are related to Hindus. Vedas are the ancient holy knowledge of the world given direct from God always, at the time of creation. I have written a lot about this and would request you to please read www.vedmandir.com.

However, shunya (zero) is created but God is not made by anybody else instead Almighty God creates universe. Shunya is also space, which is also created by God. So God is above space, beyond calculation, beyond imagination and beyond description. Yet God has unlimited qualities for
example, Yajurveda mantra 40/8 says that God is everywhere, He has no shape, no nervous system, nobody can make hole in Him, He is Almighty and does not require any assistance from anybody else. He is eternal, self sufficient, cannot be seen with eyes, beyond mind. He creates universe, nurses and destroys and again nurses and again creates. Just a small portion of His power creates universe and His great quality is also this that the whole universe which is seen by us is nothing because the Almighty God is greater than this creation. He gives birth according to our deeds (karmas) He is witness of all karmas being omnipresent and omniscient, etc., etc., that is the God has unlimited qualities and powers.

(ii) Yes, Vedas as well as Manusmriti says about four yugas, please. Each yuga has a definite time-period which is appended below.

About Yugas

Manusmriti gives the proof in its chapter one that present time of the earth is 7th Manvantar. Uptil now 6 manvantar have passed. Those are Swayambhar, Swarochisch, Ottmi, Tamas, Ryivat and Chakshash, now its 7th manvantar. 71 chaturyugi = 1 manvantar.

There are four yug – Satyug, Treta, Dwapur and Kaliyug.

Satyug = 17 lakhs 28 thousands years

Treta = 12 lakhs 96 thousands years

Dwapur = 8 lakhs 64 thousands years

Kaliyug = 4 lakhs 32 thousands years

The total of four Yugas comes to be 43 lakhs and 20 thousands years which is equal to one Chaturyugi. 71 Chaturyugi i.e., 30 crore 67 lakhs and 20 thousands years equal to one Manvantar and 6 Manvantar have yet passed whose calculation comes to one Arab 84 crore 30 lakhs and 20 thousands years. This is 7th Manvantar and 28 Chaturyugi and the present Kaliyug has passed its time of 5002 years. So, uptil now the age of the earth and Vedas is one Arab 96 crore 8 lakhs 53 thousands and 2 years. Bhagwat Geeta shlok 8/17 also says about this fact.

14 Manvantar= 1 Kalp.

Lalit: Swamiji in one of your reply you told a married couple who want a baby boy that after keeping brahmacharya for 1 year they would 99% have a boy child. But why not a girl child.What if somebody only and only want a girl child, what should that couple do.
Thank you.
Swami Ramswarup: In this connection, I would advise you to read my book “ Brahamcharya- Dukh Nivarak Divya Manni” (in Hindi) worth Rs. 100/- excluding postal charges. In the book, the method of obtaining female baby/male baby has been given. Matter being lengthy, I’m unable to explain here, please.
