When one goes through information about Hinduism and it’s Practices,one would find that each and every practice is loaded with information that signifies some fact or the other which underscores the Core Belief of Sanatan Dharm.
I have written various aspects of Hindu Rites and their significance and meaning.
And about Sankalpa,which is recited by Hindus on both auspicious and inauspicious occasions.
Sankalp is the Right Determination,be it in thoughts,Words or Deeds.And Sankalpa contains portions which Geotag the performers.
It also refers to the Time frame when the Act is performed, indicating the Aeon,day or night parameters of the Aeon,Year, Movement of the Sun 🌞,Season,Month,Star ruling that day ,Movement of the 🌒,and Day.
Hinduism considers Time to be Eternal and A stream. Time is cyclic.What we perceive as yesterday, today and tomorrow is nothing but the instrument of our minds through which we perceive.
As such , essentially there is nothing in the Universe that is good or bad.
This includes Days as well,though there are good days and bad days indicated by the Almanacs, Panchanga.
However,days do not determine what happens to you , either Good or Bad.
The reason why they are called as good and bad are is determined depending on the actions performed by you in the past and in the present.As you sow,so you Reap. In Hinduism you can not escape the consequences of your actions, whoever you might be,even of you are an Avatar. God is not above Cosmic law.
The indication a day, star gives you as good or bad is but a forewarning that good or bad, from your standpoint, may befall as a result of your actions.
Yet there are two occasions which are classified differently.The are exceptions to the Rule.
Performance of Karma, in accordance with the procedures laid out in Vedas,the Scripture of Hindus ,and Smritis, that is remembered practices, on specific days- these days are called Auspicious days,Subha Thithi.
On the other hand, death,which is not in our hands and a Harbinger of Rebirth and a beginning of new birth and deaths or merging with the Reality,is not considered auspicious. However Hinduism does not place the blame on the day.
Based on these two principles, Sankalpa makes a fine distinction.
One may note in the Sankalp, when done for auspicious occasions, it reads ‘Subha Thithou’.
This term is used for Ayush homas,Upanayan, Marriage etc.
But for Grahana, Sraddha,Pitru/Mahalaya Paksha, Amavasya ,the Sankalp reads thus.
There are Karmas which are beyond us and as such are classified as days that augur well for Good passage in Life.
