Yes, the phrase "Hans pe Sawar Hoke Aaja Mori Maiya Saraswati" is a line from a Vandana (devotional song) dedicated to the Hindu goddess Saraswati.

Explanation:

• Hans (Swan): Saraswati is often depicted riding a swan, which symbolizes purity, knowledge, and discrimination.
• Sawar Hoke Aaja: Means "Come riding on".
• Mori Maiya Saraswati: Means "My Mother Saraswati".

The line is a plea to Goddess Saraswati to come and grace the devotee with her presence.

Vandana's are devotional songs that often praise a deity and request blessings.
