Ego implies duality.There is only one ego, which is physical based. Yogic bliss is based on ego. Since yogi experiences bliss as a person. But in spiritual sense, the bliss is non dual nature of the self. For illustration the nature of the soul or consciousness, the innermost self is like deep sleep. Deep sleep is unconscious bliss,where, the mind or duality is absent.When the mind consciously enters its non dual nature in the midst of duality, through wisdom, it is non-dual self-awareness. The ultimate reality or Brahman.
The yogic bliss is impermanent, as soon as yogi comes out Samadhi he is again in the clutches of duality. But the spiritual bliss is eternal, because it is based on the soul, the innermost self.The author of the yogic bliss is ego. The author of the spiritual bliss is the formless soul or consciousness, the innermost self .
Yogic bliss is part of the duality, for even
if it did last all day, it disappears in deep sleep. The soul, the innermost self, was present before
and after the Yogi enters yogic Samadhi. When he says or thinks anything, the soul or consciousness,the innermost self is there first. It is always there whether he has got duality or not.
Hence yogic Samadhi cannot produce non dual wisdom.
