Sanatan Dharma (An eternal way of living) culture & practices

1) Rangoli with rice floor

Ever wondered why do our moms and aunts decorate the front entrance of our house with rice flour ? I though below explanation fit our understanding.

Rangoli with rice floor, in front of every household is done with the intention of feeding the ants.

2) What are the uses of a cow besides milk,ghee,butter etc ?

 Cow dung is different from  the manure.

 The cow dung is the only dung on which the dung beetles “geotrupes   stercorarius” breed. These beetles  make  small tunnels  under the dung and carry the dung into the earth and stores it. 

     These tunnels made by them,house earthworms, wherever there is high beetle activity  there is an increase in earthworm  breeding ,this increases the water infiltration on an average of 129% each extra inch. (25mm) of water absorbed 27225 gallons/ per acre (254530, 1/hc) of water to the soil reducing both flooding and drought . All this apart from increasing the fertility of the soil.

3) Why should we read "Mahabharat" ?

Chandra means moon.Moon is the ruler of the MIND (chandrama manso jaayathe..) according to Vedas. 
Mahabharat deals with the different aspects of the MIND, through each character in the story. The whole story is about play of the faculties of the MIND.

The story especially  is meant for us to analyse human mind,its actions and reactions. If one hangs on to the story aspect without getting to underlying theories,toil of our Rishies who have crafted these theories into stories will be completely lost. They are NOT MORAL stories or dictation of a RELIGION. They are stories of humans with all their plus and minus points, setting one to THINK and make proper choices.. 

4) How do we explain the concept of "Rebirth/ Reincarnation" scientifically ?

Universe is made of two things matter and energy. The law of physics states that matter can be created and destroyed, while energy cannot be created nor destroyed. But energy can be transferred from matter(form) to matter (form). This sprit or athma or soul as we call it is this ENERGY.
When the physical body  (matter) dies , the energy /athman/soul leaves the body/matter and enters another matter/body , this transfer of energy from one matter to another matter  is what we call REBIRTH.

Now what is Karma? karma is action, which decides the vibratory frequency in the energy.Good karma increases the frequency while bad karma decreases the frequency. Even a thought, good /bad has the same effect on matter (body).

5) Why do people worship an Idol (India) ?

Worshipping an Idol serves as a primary tool to many who need it as medium to access the divinity. This process methodically takes one, from Akara  (form) to Nirakara ( Formless ) 

This, methodical learning brings in a maturity to understand ,and accept that both (FORM and  FORMLESS ) are a part of one’s growing.Jumping to the Formless, without understanding results in intolerance.

 Evolutionary status of every man is different.Hence one chooses the medium which is most suitable for his/her progress. This is the accomodative thought of Sanathana Dharma.  Sanatan dharma believes every soul should grow at its own pace. Imposition of any thought is against its ethos. 

This is the reason there is no One single HOLY BOOK for Hinduism. You find MULTIPLE methods of teachings through  Shruthis ,Smrithis  Puranas, Rituals etc all helping a gradual progress leading them to the ultimate Truth./ Paramathman/Bramhan .
