Who are we?
God is in you is real you. Stop searching outside. Realize the Super Consciousness in you...
see Supreme Being in you and all around you.
Live in the present because that is what all is there.

We are:
  1. a Soul which is Consciousness or life force,
  2. a Body which is substance, and
  3. Rhythms which are waves/energy.
Or Body-Mind-Spirit exist in Three planes:
  1. Astral/Spiritual - Soul/Spirit
  2. Mental or Mind;
  3. Physical; Body;.

Every thing is like a ray of light (or a wave pattern) from the universal source Narayanam. Originating from source, returns to the source.

Heart represents characters like softness, care, love, affection, motherly feelings. It is considered feminine
Brain represents mind, though it is not mind. The right side of brain has the masculine qualities like logic, valour, organized thought process. Left side of brain is considered as feminine with characters like intuition, creativity, and superstitious belief. All humans have both masculine and feminine qualities. So, siva linga takes ardhanari form

I am not any belief system. I do not need any scriptures, rituals or practices. I am the Supreme being.
You don’t need to run away from daily life to realize god. That Supreme Being is in you. Do your duties. Control ego and anger. Finally, the most important part is to realize that you are part of this Nature and not above it – Everything in this universe is nothing but – the Supreme being.
It is the energy which is the only thing that exists. I, Me, Myself, and thoughts of separation from the supreme is only illusion due to the duality. We are distorted images of God in the mirror

Atman and Kosha

A Kosha (कोश), means or a covering of the Atman, or Self according to Vedantic philosophy. There are five Koshas, which are often visualised as the layers of an onion. According to the yoga tradition, every one of us has five layers or bodies. Human beings consist of a material body or Annamaya-kosha built from the food they eat. Inside this is another body made of life energy or prana or Pranamaya-kosha. Within the vital force is mental body or Manomaya-kosha. Deeper still lies another body comprised of intellect or Vidnyanamaya-kosha. Hidden inside is last body Anandamaya-kosha, experienced as happiness, delight, and bliss. These five layers or bodies are called koshas.
The Annamaya-kosha is gross while the other sheaths are subtle. After death, a Jiva’s Annamaya-kosha and Pranamaya-kosha do not remain, but Manomaya-kosha, Vidnyanamaya-kosha and Anandamaya-kosha remain with self.
I am the Atma, the consciousness, an independent principle totally different from the body. It is not visible, but known, because it activates, the body. Atma is not an object to be looked for. As it is never a knowable object, it does not come under: (i) Known object or (ii) an unknown object. Atma is behind all senses/organs and experiencing the entire world. We can only say “I am Atma.”

Astrological Interpretations

Creation and life events are based on astronomical patterns during birth. We are body (matter) - Energy (force or power) - Thoughts (mind, intellect..). Lagna, sun and moon positions during birth determine above three aspects.

Consciousness

Consciousness is the entire reality. There was a big bang at the beginning of things and it spread. We human beings, are little patterns on the end of it. Billions of years ago, we were a big bang, but now we're still the big bang, not the result of the big bang. We all are original force of the universe, the primordial energy of the universe. So let us not separate ourselves from it. Through our eyes, the universe is perceiving itself. Through our ears, the universe is listening to its harmonies. We are the witnesses through which the universe becomes conscious of its glory, of its magnificence. All of “us” are the universe. All of “us” is the process.

What is death

We already know what happens at death. We lose consciousness, our brains die and can't be restarted and it's over. From science perspective, death is opposite of birth or absence of life (like darkness). Humans die because their only purpose in life is to pass on their genes and give way to next generations. From an engineering perspective, humans die because their bodies are complex systems and the accumulation of damage and malfunctions is "aging". Humans live to learn and experience life. It's just that some of us don't want to believe this is true.
Living beings reproduce or convert energy from food. We are alive, but our heart or some organs clearly is not. So the alive one is made up of dead "things". A bacterium, smaller than even a single cell in our body is alive. Bacterium too is made of dead stuff. So maybe life is just a pattern or net work of specific combinations of dead things.
People claim dead people are still alive in the spirit realm to make us feel better. Some medium say they can receive messages from dead. No one can prove that there is no afterlife. But there is lots of evidence of people fooling themselves and others with fakery. Near Death Experiences happen in a living brain that is shutting down not something that happens after the brain has ceased to function.
Reincarnation is belief in life after death. There is a circle of Karma that leads to birth, death and rebirth again. This is a continuous cycle, because when one dies only the body perishes but not the soul. The soul leaves the body, and moves onto another. It is just a belief, which can not be proved or disproved.
