The name Keyana is believed to have originated from the Sanskrit language, which is an ancient Indo-Aryan language that was prevalent in the Indian subcontinent. The name is thought to be derived from the word "keya," which means "body" or "physical form." This suggests that the name Keyana may have been associated with physical beauty or strength.

In ancient Hindu texts and scriptures, such as the Vedas and Upanishads, there are references to the concept of "keya," which is closely tied to the spiritual and philosophical beliefs of Hinduism. However, there is no direct mention of the name Keyana itself in these texts.

The earliest recorded use of the name Keyana can be traced back to the 7th century CE in parts of present-day India and Bangladesh. During this time, the name was primarily given to female children born into Hindu families.

One of the earliest known individuals with the name Keyana was Keyana Devi, a Hindu princess who lived in the 9th century CE in the region of Bengal. She was renowned for her beauty and her patronage of the arts and literature.

Another notable figure was Keyana Bharati, a 12th-century Hindu scholar and philosopher who made significant contributions to the study of Vedanta, a branch of Hindu philosophy. She was born in 1118 CE and lived in the city of Varanasi, which was a prominent center of learning at the time.

In the 14th century, Keyana Namaskar was a renowned Hindu mystic and spiritual teacher who was revered for her wisdom and her ability to guide seekers on the path of self-realization. She was born in 1312 CE in the region of Gujarat and traveled extensively throughout India, sharing her teachings with people from all walks of life.

During the Mughal era, which spanned from the 16th to the 19th century, there was a Keyana Begum, who was a prominent figure in the royal court of the Mughal Empire. She was born in 1572 CE and was known for her philanthropic efforts and her patronage of the arts and architecture.

In more recent times, Keyana Ghosh was a notable Bengali writer and social reformer who lived from 1879 to 1953. She was a pioneer in the field of women's education and empowerment in India and wrote extensively on issues related to gender equality and social justice.
