Someone assured this question
My reply was
Depends on what level you are at and what you seek
- Smoothest book – the divine Romance
- Wow book – how to talk with God
- Sheer Yoga – God talks with Arjuna
- Intellectual book – science of religion
Talking about books there is a nice book by Donald Hoffman on consciousness.
This would be for people who want to understand consciousness not experience it
The case against reality
My opinion. Why bother. Just experience it!
