Sage Patanjali's Yoga Sūtras on Soul, Mind, God (Baba), bodiless state and becoming free from past impressions (sinful actions):
The skill of yoga is demonstrated by the conscious non-operation of the vibrational modes of the mento-emotional energy.
Then the perceiver (soul) is situated in his own form.
The vibrations in the mento-emotional energy are five-fold being agonizing or none-troublesome.
They are correct perception, incorrect perception, imagination, sleep and memory.
That non-operation of the vibrational modes is achieved by effective practice in not having an interest in the very same operations.
That highest non-interest ( Vairagy – disinterest) occurs when there is freedom from desire for the features of material nature and thorough awareness of the spiritual person (soul).
Verse 18 and 19
The other state is the complete departure from the level where the remaining impressions lie in the mento-emotional energy. Of those who are diffused into subtle material nature and those who existing in a bodiless state, their psychology has that content.
Or by the method of profound religious meditation upon the Supreme Lord.
The Supreme Lord is that special person who is not affected by troubles, actions, developments or by subconscious motivations.
There, in Him, is found the unsurpassed origin of all knowledge.
He, this particular person, being unconditioned by time is the (Supreme) Guru even of the ancient teachers, the authorities from before.
In regards to the great reduction of the mento-emotional operations, there is fusion of the perceiver, the flow of perceptions and what is perceived, just like the absorption of a transparent jewel.
On gaining competence in the non-investigative linkage of one’s attention to the higher concentration force,one experiences the clarity and serenity which results from the linkage of the Supreme Soul and the limited one (soul).
Chapter2: Verse 1
profound religious meditation on the Supreme Lord is the dynamic kriya yoga practice.
Purification, contentment, austerity and profound religious meditation on the Supreme Lord are the recommended behaviors.
From the profound religious meditation upon the Supreme Lord comes the perfection of continuous effortless linkage of the attention to that Divinity.
