After Caine's sin, he was cursed by God with the vampirism, but He gave the Kindred one chance at salvation: Golconda. Caine refused it but the Salubri Antediluvian, Saulot, achieved it and taught the other Salubri how to obtain it. Golconda was perfect for the Salubri, because of their compassionate nature.
However, after Saulot's demise at the hands of the Tremere, nobody really knows how to achieve Golconda. While many Kindred of the modern times consider it a myth, others like the Inconnu know that it is true and not just some mirage.
The Path to Golconda is very hard and only after long years of searching someone can achieve this state. The known steps to achieve Golconda are:
1. Feeling remorse for the vampire's sins.
2. Raising Humanity's levels.
3. A challenge named suspire which can be passed or failed. If a Kindred fails his or her's suspire, he or she would never achieve Golconda.
Achieving Golconda gives the vampire exceptional benefits and powers like:
1. Never having to worry about frenzying, because of the balance which now exists between (s)he and the Beast.
2. Werewolves never harm a Kindred in Golconda, because they aren't Damned anymore.
3. Disciplines become more powerful and the Golconda Vampire can learn advanced forms of those Disciplines.
4. The amount of blood needed for sustenance is decreased tremendously.
5. It is not known for sure, but it is said that a Vampire in Golconda can resist sunlight or can return back to his or her human form.
In order to maintain this state, a Kindred must maintain a high degree of morality and compassion. If his or her Humanity drops below 7, the abilities given by Golconda will be lost. However, if the vampire manages to raise his or her Humanity back, the tremendous powers of this enlightened state would return immediately.
Golconda vs. BardoEdit
First and foremost, any positive effect that Bardo gives to the vampire is temporary, as long as the Kindred maintains the Discipine. Golconda's effects never wear out, except when Humanity falls below 7, but for a Golconda achiever, this is an almost impossible thing to happen.
Secondly, Bardo is a Discipline that comes from denial. The inner Beast is viewed as an enemy who must be subdued. Golconda, however, is based on acceptance and balance. The Golconda achiever knows that the Beast is part of him, not unlike as the Humanity is part of him.
And probably, the greatest difference is that Golconda is a state of existence and Bardo is a Discipline.
