Tīrtha-vaṃśa Upadeśa: Instruction on the Fruits of Sacred Waters
(मुहूर्तानां त्रय॑ पूर्वमह्नः प्रातरिति स्मृतम् । जपथध्यानादिभिस्तस्मिन् विप्रैः कार्य शुभव्रतम् ।।

毗湿摩说道：“一日之初三牟呼尔多，被称为清晨。于此时，婆罗门当以诵念（japa）、禅观等修持吉祥之行，以求自身灵益。其后又三牟呼尔多名为‘僧伽婆’（saṅgava）；僧伽婆之后，再三牟呼尔多称为正午。僧伽婆时宜料理世务；至正午则当沐浴并行暮晨交替之礼（sandhyā）。正午之后，再三牟呼尔多称为午后；此为一日第四分，适于祖灵之事。其后又三牟呼尔多称为黄昏，智者以之为昼夜交界之际。婆罗门家中施罗陀终了时，诵‘svadhā’据说能使祖先欢悦；而刹帝利家中，则应以‘愿祖先欢喜’作结。”

Educational Q&A
Bhīṣma teaches a dharmic ordering of the day: allocate specific time-blocks (muhūrtas) for spiritual practice (japa, dhyāna), worldly responsibilities, purification and sandhyā rites, and ancestral duties (śrāddha/pitṛ-kārya). Right timing is presented as part of right conduct.
In the Anuśāsana Parva’s instruction-setting, Bhīṣma continues his didactic discourse by defining traditional divisions of daytime and prescribing appropriate activities for each, including how to conclude a śrāddha with role-appropriate formulas for brahmins and kṣatriyas.
