Vishnu devta has an astral or sukshma sarir. Vishnu is part of Shivji’s male trinity not female trinity. It is Original God who is the ultimate energy provider to make Vishnu devta. Without Original God’s energy and power Vishnu or Shiva cannot exist. Do you understand this simply statement. Without energy nobody can exist on Earth, not even Vishnu or Shivji or me…Don’t mix up Original God with false religious beliefs and worships.
