Time of union or conjunction. There are three सन्ध्यास् in a day. These are morning सन्ध्या ( प्रातःसन्ध्या ), noon सन्ध्या ( मध्याह्न सन्ध्या ) and evening सन्ध्या ( सायं सन्ध्या ). The meeting time of night and day, is morning सन्ध्या , the joining time of the first half and the second half of the day, is noon ( मध्याह्न सन्ध्या ), and the joining time of day and night, is evening सन्ध्या ( सायं सन्ध्या ). Brahmins should keep the three सन्ध्यास् properly. The morning सन्ध्या is of three kinds. Good, Medium and Bad. When the morning stars are seen and the sunrise is approaching it is good morning; when the stars are not seen and the sun is not risen it is medium सन्ध्या and the morning time after the sunrise is bad सन्ध्या . In सायंसन्ध्या also there is this difference of time, as good, medium and bad. The time till the sunset is good; the time after the sunset and before the rising of the stars is medium and the evening after the rising of the stars is bad. In the Vedas it is metaphorically mentioned that Brahmins are trees, and the three सन्ध्यास् are their roots, the Vedas, their branches and the rites and rituals ordained in the Vedas their leaves. From this it is clear that Brahmins should on no account leave unobserved, worships at these three सन्ध्यास् . The Brahmin who does not observe these three सन्ध्यास् carefully will, in his life time, become a शूद्र and after the death, will be born again as a dog. Moreover the Brahmin who does not do the three evening, morning and noon worships, will have no right to conduct any other Vedic rites.

After the sun-rise and sun-set, within three नाज़्हिक s (a नाज़्हिक -24 minutes) the morning and evening worship should be finished. There is atonement ordered for morning and evening prayers conducted after the stipulated time. (Devī Bhāgavata, Skandha 11) .
