A heartfelt greetings to everyone !
I wanted to add a link to Ven. Lal Sir’s answer.
Gandhabba or Manomaya Kaya is an important concept in Buddha Dhamma. So it is essential to get a good idea about what this Gandhabba or Manomaya Kaya is like.
I found a youtube video depicting Astral body and Astral travel. This might be helpful for those who want to get some perception about “Mental body”.
Please see – Astral body and Astral travel
Hope this helps
MAY ALL BEINGS ATTAIN NIBBANA !!!
