Vaikuntha essentially means a realm without Kuntha (stress, worry, anxiety, fear). It is one of the several abodes of Vishnu said to be accessible to those that ascend to a very high level of vibration and are aligned with the energies of Vishnu.
As Dream pointed out, it is very very very difficult for most humans to get there. During an astral journey, when I once tried to venture there, I had to encounter Sudarshana, a massive discus of light that would not let me pass. Sudarshana, often depicted as a weapon, is the dynamic aspect of Vishnu’s energy that burns away all negativity with its fiery blaze. This mechanism is a guard to this realm (every realm has its own mechanisms).
So, without the will of Vishnu and Sudarshana, it is impossible to ever glimpse this realm, forget encoding it. This speaks a lot about Dream’s capabilities as well.
The energy is a “taste” of the realm, like watching its picture, experiencing a waft of fragrance etc. Due to the very powerful and sanctifying nature of this realm, a taste of its energy is more than enough to offer many benefits:
- Protection from harm (Vishnu’s main function is sustenance of creation, and hence protection)
- Peace like one has never experienced before
- Bliss and Joy
- Longevity (Vaikuntha is visualized as floating on an ocean of nectar, so the beings here do not age or die)
- Prosperity (Vaikuntha is also the realm of Goddess Lakshmi, the bestower of riches, wealth and prosperity)
I was able to experience energy of this in several ways - images (of milky ocean, blue/violet flashes), fragrance (jasmine and sandalwood), taste (charged water tasted different and sweet).
