Sutra 1.21

Sutra I.21 तीव्रसंवेगानामासन्नः॥२१॥
(tivra samvegaa naam asana-ha॥21॥) 
This state is not so difficult to attain if one is focused and fervent about reaching it.

Even though Patanjali’s philosophy leads us where we cannot really go as it is so far from our secular world, the idea is that even while living this life one can develop spiritually by dissociating more and more from the experiences and thoughts that constantly drive us.
