'yukta Asita matpara:' were Krishna's words.
One who doesn't meditate on Him but instead thinks of taming Indriya-s & all powerful Desire by himself won't ever beget Atma-cintana. How can he do dhyana bereft of Atma-cintana?
Yoga has anga-s like pratyAhAra, dhArana, dhyAna etc.. with their ultimate phala as Moksha
Shastras call it as 'pUrvapUrvAbhAvat uttarauttarotarasya abhAva: sUcita:'
One who fails to control his Mind won't develop jnana required for Atma-sAkshAtkAra
Without jnana, there's no shanti for him. Without shanti, where's the sukha?
Sukha here means the act of disassociating oneself from all the desires fuelled by indriya-s
Same as (A)
