Anonymous: What is the significance of upanayanam/thread ceremony? Is here any scientific reason behind it? Thanks
Swami Ram Swarup: Upnayan Sanskar is performed while performing pious yaj from ved mantras. To obtain the blessings of almighty God and acharya to proceed with further education worldly as well as spiritual.

Vedas are scientifically true, so scientific impression is automatically is obtained by the aspirants.

Ashok: Swami ji namaste. Swami ji “shree” ka arth kya hai, Evam vedik padditi me swastik chinha ka koi matlab hai?
Swami Ram Swarup: Ashok beta my blessings to you for a long happy life. Shree ka arth hai Dhanwan evam aishwarywan.

Vedic paddti mein swastik chinha ka koi description nahi hai, yeh pauranic hai aur manushyon ka banaya hua hai.
