You are correct. In traditional Hindu medtitation of all sorts, there is no “emptying the mind”. There is striving to still or quiet the incessant flow of the mind’s desires and selfish thoughts, but only by positive meditation on God’s attributes through various means.
Even Patanjali was very clear about this.
Westerners like “yoga” that is divested of its original intent and have made up their own version. With assistance from various very inauthentic “gurus” who make up their own crap as they go along to please rich westerners with easy virtue!
Don’t they also use yoga only for its physical benefits in India as well though? I know it is broken down by different names for different levels such as hatha yoga for the physical aspect. Even there not everyone uses it as an aid to the spiritual path do they?
