- Dharma, 'the Maintainer of the Religion'
- Yogeshvara, 'the Controller of the Yoga'
- Amala, 'the Immaculate One'
- Îshvara, 'the Supreme Controller'
- Purusha, 'the Original Person'
- Avyakta, 'the One Unmanifest'

[Srimad Bhagavatam 11.5.23]

Nara-Narayana twin
In this Yuga Lord Vishnu incarnates in a white colour, and wears tree bark and a black deerskin as an ideal meditative Brahmacari yogi, like Lord Kapila-Deva or Lord Nara-Narayana [Atma and Paramatma as twins?...].

Those who are self-realized in this age know this Supreme Being, Lord Vasudeva, as Paramatma. Absorbed in meditation, the sages of Satya-yuga perceive Him in various four-armed transcendental forms within their hearts and worship Him.
