Varna and Gothra - in two lines

Jai Guru,

Definitions of Varna & Gotra in one line:-

1. Varna is a grouping of varities of similar inborn instincts.

Notes:
- Satva Guna inborn instincts= Vipra Varna ; Rajas Guna inborn instincts= Kshtriya Varna ; Rajas-Tamas Guna inborn instincts= Vaishya Varna ; Tamas Guna inborn instincts= Shudra Varna

- Varna is by birth and can NOT be changed by a person in his lifetime, come what may. However, if a family-lineage acquires the attributes of the immediate higher varna for 7 consecutive generations then from the 7th generation that lineage will change to that higher varna. An acquired instinct takes 7 generations to become an inborn instinct.
- Not only human beings, rather the entire material creation has originated in these 4 different Varnas, including planets,universes,
soil,animals, plants,birds, bees & all macro & micro-orgnaisms.

2. Gotra is a Rishi lineage.

Notes:-
- All human beings ( in fact all jeevas) are progeny of certain Rishis. Progeny of a Gotra share the same blood and are blood-relatives. They never marry among themselves as it will amount to inbreeding.

-Gotra is also by birth, and can not be changed in a person's lifetime.

These are NOT mythology, rather hardcore science.
