हयमेध-यज्ञोपक्रमः — Commencement of the Aśvamedha Preparations
ततस्सुमन्त्रमानीय वसिष्ठो वाक्यमब्रवीत्।निमन्त्रयस्व नृपतीन्पृथिव्यां ये च धार्मिका:।।1.13.18।।
brāhmaṇān kṣatriyān vaiśyān śūdrāṃś caiva sahasraśaḥ | samānayasva satkṛtya sarvadeśeṣu mānavān || 1.13.19 ||
Gather, with due honor, thousands of people—brāhmaṇas, kṣatriyas, vaiśyas, and śūdras—from every region.
Then Vasishta, having summoned Sumantra said to him "Invite all the righteous kings on earth".
Dharma in a royal-sacred event includes inclusive participation and respectful treatment across social groups.
Vasiṣṭha expands the invitation beyond kings to the wider populace from all regions, ensuring a grand and orderly gathering.
Lokasaṅgraha (welfare and cohesion of society): bringing communities together with honor rather than exclusion.
