Veet Raaga Vishyam Vaa Chittam
Raaga: Aattachment to pleasure
Vishayam: Objects of senses
(To still oneself on) a chitta which is free from attachments also (purifies the chitta).
You become what you follow, if you follow the sun, you exude its brightness, if you follow a monkey, you end up dancing around trees. Therefore look for a being who is him/herself free from the bondages of maya (attachment) and still yourself on him/her, your bondages will open.
Swapna Nidraa Gyaan Aalambanam Vaa
Gyaan: Knowledge through experience
Aalambanam: Depending on, relying on
Drawing on the gyan from dreams and sleep pattern also (purifies the chitta).There are four states of mind – conscious, unconscious, subconscious and super-conscious. State of dhyan is the state of super-conscious. Dreams pertain to subconscious, which plays before us our various thoughts and desires juxtaposed with things we see or events that occur around us. However at times, certain subtle experiences also happen in a dream state, which is the activation of super conscious. By studying these various states of mind through practice, being able to differentiate between them and hence, gaining control over them, the chitta gets purified.
Yathaa Abhimat Dhyaanaat Vaa
Yathaa: As per
Abhimat: Individual choice
Dhyaanaat: Through dhyan
Through dhyan on an object as per individual capacity and choice also, (chitta gets purified).
No two individuals are same, nor are their desires similar. Yoga is therefore an individual journey and as per individual capacity, whatever satisfies his/her need, one may choose a focus which he/she is able to still him/herself on, when he/she is able to still on that one thing/focus, the chitta will get purified.
