Vismaya means amazement that is capable of holding one’s total attention; yoga here means union with the Supreme Self; bhūmikā here refers to the different stages of union withe the Supreme Self, referring to the different states of Yogī’s consciousness while attaining the Supreme Consciousness.When the Yogī moves towards
When the Yogī moves towards turya, he is totally bewildered and is delighted in the experience of the manifestation of various objects as an expansion of his entire group of his senses. The intensity of his bewilderment increases progressively though he remains calm and smiling, aspires for higher states of consciousness and the resultant bliss.
When a yogi transcends normal stages of consciousness and moves towards turya, he begins to feel the bliss and becomes bewildered by its effect. This can be compared to a person from a hot terrain making his journey to a hill resort. When he moves towards the hill, he could feel the change in weather conditions from hot to cold. When a person progresses spiritually, he has to make a beginning to transcend the three known levels of consciousness to the next higher level of consciousness, the turya stage. He can realize Śiva only in the highest level of consciousness, which means that his concentration should be totally focused on Śiva and Śiva alone. If any other thoughts impregnate his mind, he will not be able to realize the Absolute. When he makes significant progress, the level of bliss that he enjoys also becomes strong and pulls him further towards Śiva. When he begins to taste the bliss, he gets engrossed in the stage of supreme happiness or ānanda that is full of surprises. He is surprised because, he has not experienced that kind of ānanda earlier.
It is also said that the experience of the Yogī with the psychic centres of his body – from mūlādhārato ājñā cakra-s, is in no way a comparison to his consciousness when he experiences the Supreme consciousness of Śiva. Once the Yogī experiences the Supreme Consciousness of Śiva, his different experiences in his psychic centres are incomparable to that state.
Gabriel Pradīpaka in his Svātantryasūtram (I.16) describes this state of Yogī as, “naparamārthātpṛthak kiñcidapyasti”, which means there is nothing, apart from the Highest Reality. TheYogī only aspires for this highest state.
