I am a Brahmin, i always wonder when people keep asking what is the gothram that you keep talking about. I try explaining to them, about how we have a lineage. The roots from where we come from. Most of the times i find people staring at me blankly.....
so here is my research on the lineage

A Gotra is the lineage or clan assigned to a Hindu at birth. In most cases, the system is patrilineal and the gotra assigned is that of the person's father. Other names used to refer to it are Vansh, Vanshaj, Bedagu, Purvik, Purvajan, Pitru. An individual may decide to identify his lineage by a different gotra, or combination of gotras. For example Lord Rama was Surya Vansha, also known as Raghu Vansha. This was because Lord Rama's great-grandfather Raghu became famous.
The term gotra, itself, according to strict Hindu tradition is used only for the lineages of Brahmin, Kshatriya and Vysya families. A Gotra relates directly to the original seven or eight Rishis of the Vedas. In this sense, Lord Rama did not have a Gotra, and in rituals his Gotra would be the Gotra of his Brahmin priest. This practice is still common today as it was in ancient times according to earliest Hindu sources. Therefore, Gotra has always been only a Brahmin lineage that descends from seven or eight rishis associated with the Saptarishi or the seven stars of the Great Bear constellation as according to original Hindu Vedic system. The word "Gotra" means "ray." In Brahmin tradition, it is the duty of the Brahmin to keep his particular ray alive by doing daily rituals that he may transmit the power of that ray to others for the benefit of mankind. When the "ray" is extinguished, so is that particular beneficial magical stream dead to the human race and that power lost to mankind forever. Hence the importance of a Brahmin's daily Sandhya.
The Sanskrit term "Gotra" was initially used by the Vedic people for the identification of the lineages. Generally, these lineages mean patrilineal descent from the sages or rishis in Brahmins, warriors and administrators in Kshatriyas and ancestral trademen in Vaisyas.

Recently, the term "gotra" has taken broader meanings to include any lineage, Brahmin or otherwise. Therefore, today, other terms are considered synonymous with gotra and the distinct meaning of the word and the esoteric connotations are lost to many, even within the Brahmin community.

A common mistake is to consider gotra to be synonymous with clan or Kula. A kula is basically a set of people following similar rituals, often worshipping the same God (the Kula-Devata - the God of the clan). Kula has nothing to do with lineage or caste. In fact, it is possible to change one's Kula, based on his faith or ista devatha.
It is common practice in Hindu marriage to enquire about the Kula-Gotra meaning Clan-Lineage of the bride and bridegroom before approving the marriage. In almost all Hindu families, marriages within the same gotra are prohibited since people with same gotra/gothra are considered to be siblings. But marriage within the kula is allowed and even preferred.

Marriages and gotras

Marriages within the gotra ("swagotra" marriages) are banned under the rule of exogamy in the traditional matrimonial system. People within the gotra are regarded as kin and marrying such a person would be thought of as incest. In some communities, where gotra membership passed from father to children, marriages were allowed between uncle and niece, while such marriages were forbidden in matrilineal communities, like Malayalis and Tuluvas, where gotra membership was passed down from the mother. A much more common characteristic of south Indian Hindu society is permission of marriage between cross-cousins (children of brother and sister). Thus, a man is allowed to marry his maternal uncle's daughter or his paternal aunt's daughter but is not allowed to marry his father's brother's daughter, a parallel cousin, who is treated as a sister.

Hope i have cleared the doubts people have........I am Atherya one of the Sapta Rishis.......

The Significance of the Symbol Om


The symbol Om (also called Pranava), is the most sacred symbol in Hinduism. Volumes have been written in Sanskrit illustrating the significance of this mystic symbol. Although this symbol is mentioned in all the Upanishads and in all Hindu scriptures, it is especially elaborated upon in the Taittiriya, Chandogya and Mundaka Upanishads. From the Katha Upanishad (- I, ii, 15-17):
The goal, which all Vedas declare, which all austerities aim at, and which humans desire when they live a life of continence, I will tell you briefly it is Om. The syllable Om is indeed Brahman. This syllable Om is the highest. Whosoever knows this symbol obtains all that he desires. This is the best support; this is the highest support. Whosoever knows this support is adored in the world of Brahman.

The symbol of Om contains of three curves, one semicircle and a dot. The upper curve symbolizes the waking state; the lower curve denotes deep sleep (or the unconscious) state, and the right-side curve (which lies between deep sleep and the waking state) signifies the dream state. These three states of an individual’s consciousness, and therefore the entire physical phenomenon, are represented by the three curves. The dot signifies the Absolute (fourth or Turiya state of consciousness), which illuminates the other three states. The semicircle symbolizes Maya and separates the dot from the other three curves. The semicircle is open on the top, which means that the absolute is infinite and is not affected by maya. Maya only affects the manifested phenomenon. In this way the form of Om symbolizes the infinite Brahman and the entire Universe and the world. Aum is made out of the three gods Shiva and Ganesh and Gayatri.
Uttering the monosyllable Om, the eternal world of Brahman, One who departs leaving the body (at death), he attains the superior goal.
-Bhagavad Gita, 8.13

Vibhuti, a word of Sanskrit and several other languages of India. Literally, it has several meaning including all pervading; superhuman power; and wealth. Vibhuti is also the name for sacred ash used in religious worship in Hinduism, especially connected with Lord Shiva. The ash has several symbolic meanings. Placed on the forehead of devotees, it covers the mark of the spiritual third eye of Hindu belief that sees development of mystic insight as the primary path to Self-realization. It is a reminder of one's mortality since bodies are cremated being only temporary vessels of the soul. It calls to the good of ridding oneself of selfish and base worldly desires that wrap the self in Maya (illusion) just as Shiva burned the god of desire, Kama, to ashes when he attempted to break Shiva's focus on the Divine Truth.
