“Whether Yoga is Sādhana or Siddhi?
Sādhana is the means to achieve something.
Siddhi is where something has happened.
For Siddhi to happen there has to be Sādhana, some preparation, some effort.
So how is it possible for something to be both Sādhana and Siddhi?
Each gain we make is a Siddhi.
Each Siddhi helps us to go further with Sādhana.”
