the Vāstu-puruṣa-mandala and Vastu Śāstras, do not limit themselves to the design of a Hindu temple. They describe the temple as a holistic part of its community, and lay out various principles and a diversity of alternate designs for home, village and city layout along with the temple, gardens, water bodies and nature. Exceptions to the square grid principle A predominant number of Hindu temples exhibit the perfect-square grid principle. However, there are some exceptions. For example, the Telika Mandir in Gwalior, built in the 8th century CE, is not a square but a rectangle in 2:3 proportion. Further, the temple explores a number of structures and shrines in 1:1, 1:2, 1:3, 2:5, 3:5 and 4:5 ratios. These ratios are exact, suggesting that the architect intended to use these harmonic ratios, and the rectangle pattern was not a mistake, nor an arbitrary approximation. Other examples of non-square harmonic ratios are found at the Naresar temple site of Madhya Pradesh and at the Nakti-Mata temple near Jaipur, Rajasthan. Michael Meister suggests that these exceptions mean that the ancient Sanskrit manuals for temple building were guidelines, and Hinduism permitted its artisans flexibility in expression and aesthetic independence. The symbolism A Hindu temple is a symbolic reconstruction of the universe and the universal principles that enable everything in it to function. The temples reflect Hindu philosophy and its diverse views on the cosmos and on truth. Hinduism has no traditional ecclesiastical order, no centralized religious authorities, no governing body, no prophet nor any binding holy book save the Vedas; Hindus can choose to be polytheistic, pantheistic, monistic, or atheistic. Within this diffuse and open structure, spirituality in Hindu philosophy is an individual experience, and referred to as kṣaitrajña (Sanskrit: क्षैत्रज्ञ)). It defines spiritual practice as one's journey towards moksha, awareness of self, the discovery of higher truths, true nature of reality, and a consciousness that is liberated and content. A Hindu temple reflects these core beliefs. The central core of almost all Hindu temples is not a large communal space; the temple is designed for the individual, a couple or a family – a small, private space to allow visitors to experience darsana. Darsana is itself a symbolic word. In ancient Hindu scripts, darsana is the name of six methods or alternate viewpoints of understanding truth. These are Nyaya, Vaisesika, Sankhya, Yoga, Mimamsa and Vedanta – which flowered into individual schools of Hinduism,
