I did once attempt to start a discussion on another thread on the Spiritual Heart but it didn’t evoke much response, except from Miss H!
Another spiritual teacher, Maharishikaa talks about this in most of her videos on YouTube. Here is one of them -

Once we shift the fulcrum of consciousness from head (ego) to heart (love) we can actually feel the pulse of toroidal divine energy. Now, I’ll not go into as much detail as Ramana or Santosh Sachdeva or Lahri Mahasaya or Robert Adams about this or the exact location, size, attribute etc. but suffice to say, it is the seat of our soul.
From the tantric (energy) perspective, once our fontanel (Sahasrara), third eye (Ajna/ Agya) and heart (Anahata) triangulate, the ego in head ovoid hands over the baton of awareness to God’s love in our heart centre and we begin to shift towards unity consciousness. This may be discerned by noticing that bliss suffused serenity is our default fulcrum.
