Jnana/Knowledge of the Self evokes bhakti/devotion towards the Self. It is this bhakti that acts as anchor for the mind. Yoga means union or integration. Normally mind is divided in many parallel activities consciously, subconsciously and unconsciously jointly. Most of the times inner-chatter/verbalisation goes on in the mind in the background while we perform some act. It is bhakti that integrates the divided mind and union/yoga happens.
Self Realisation or Enlightenment means direct knowledge of the Self. It is a realisation that you are impersonal awareness. This realisation takes place in the mind but may not change the unconscious mind completely since unconscious mind is programmed for several years. However, this realisation slowly changes the depth of the mind as one gets to see more clearly how thoughts arise and is therefore able to purify the mind. As mind rewires itself, the general feeling of bliss increases. When the mind steadily abides in Self, it is Self Actualisation. Self Actualisation implies happiness by default.
[Bhagavad Gita 18.54]
The above implies that the Yogi with happy mind abiding in Self neither grieves for anybody nor expects anything.
|Vaikhari Vaani||Vocal/Verbal speech.|
|Madhyama Vaani||Internal mental speech like self talk or inner talk or dream state. This happens when verbal speech settles deeper.|
|Pashyanti Vaani||When there is the absence of attachment with vocal or inner talk (like saakshi chaitanya or witness consciousness). Here, the voice is in its potential/seed form (like dreamless deep sleep state which has no expression in itself but has the potential to move either to the dream state or to the waking state). This happens when mental speech settles even deeper towards non-duality.|
|Para Vaani||Beyond speech like in nirvikalpa samadhi or when the body is unconscious like in near death experience (NDE) or in an epiphany. In this state the Self can possibly know itSelf.|
