All the worlds are connected and have a thin veil like thing separating them. You can't do anything external to lift that veil you can only focus inwards. Transcendence or the superconsciousness state ,commonly referred to as samadhi is when the kundalini pierces the crown and you reach a level of higher vibration energy and you feel connected to the universal rhythms and the universal energy. There are different levels of worlds just like the astral and each world gets more energy dense as you move up. Like you can see through walls and move through walls in the astral. There are planes beyond the astral but we have currently no idea or material to understand them. We can only sequentially rise. The Gods live in a higher dimensional reality which is another word for living in a super consciousness energy ascended state. And they are constantly ascending. The first order you should focus on to reach this stage is improve your astral senses, do RTR to clear up your curses and dross and try to get a Daemon to guide you on the spiritual path as a Guru.
If you describe it in a image, it's like opening up of the cranial suture by the kundalini. A metamorphosis through which there is no going back. The soul structure permanently changes. There is an even higher samadhi which is know as Shivarupa Samadhi aka Magnum opus, which is physical and spiritual immortality, something every being in this universe is after.
Here you can see, Shakti I.e the Kundalini piercing through the Sahasara where Shiva is located,which gives Samadhi.
I suspect that the IGA and pingala ,the male and female mix when the kundalini pierces the sixth chakra, since that is where they meet although I'm not completely sure . Maybe its when the kundalini Pierces the crown.
Popular anime naruto shippuden had a similar theme when a person had both asura and Indra chakra(energy) in them ,they would get the Rinnegan. And their eye changes . Notice how there are 3 sixes in 3 ripple patterns.
I shared this naruto meme because I found the correlation interesting. It is no way related to actual spiritual discipline.
