Ishna ji,
In Gurbani guru ji talks about Clairvoyance its called a Sidhi(Supernatural power) also called Door-Darshan(to see all).There are 18 Sidhis & Clairvoyance is one of them.
ਸਭਿ ਨਿਧਾਨ ਦਸ ਅਸਟ ਸਿਧਾਨ ਠਾਕੁਰ ਕਰ ਤਲ ਧਰਿਆ ॥
All the nine treasures, and the eighteen supernatural powers are held by our Lord and Master in the Palm of His Hand.
ਜਨ ਨਾਨਕ ਬਲਿ ਬਲਿ ਸਦ ਬਲਿ ਜਾਈਐ ਤੇਰਾ ਅੰਤੁ ਨ ਪਾਰਾਵਰਿਆ ॥੪॥੫॥ {ਪੰਨਾ 10}
Servant Nanak is devoted, dedicated, forever a sacrifice to You, Lord. Your Expanse has no limit, no boundary. ||4||5|
These are considered to be of no great merit, are interference in the Lord’s plans, and are a hindrance in the God realization
ਮਨਹਠਿ ਕਿਨੈ ਨ ਪਾਇਓ ਸਭ ਥਕੇ ਕਰਮ ਕਮਾਇ ॥ ਮਨਹਠਿ ਭੇਖ ਕਰਿ ਭਰਮਦੇ ਦੁਖੁ ਪਾਇਆ ਦੂਜੈ ਭਾਇ ॥
No one has ever found the Lord through stubborn mindedness. All have grown weary of performing such actions. Through their stubborn mindedness, and by wearing their disguises, they are deluded; they suffer in pain from the love of duality||
ਰਿਧਿ ਸਿਧਿ ਸਭੁ ਮੋਹੁ ਹੈ ਨਾਮੁ ਨ ਵਸੈ ਮਨਿ ਆਇ ॥ ਗੁਰ ਸੇਵਾ ਤੇ ਮਨੁ ਨਿਰਮਲੁ ਹੋਵੈ ਅਗਿਆਨੁ ਅੰਧੇਰਾ ਜਾਇ ॥ ਨਾਮੁ ਰਤਨੁ ਘਰਿ ਪਰਗਟੁ ਹੋਆ ਨਾਨਕ ਸਹਜਿ ਸਮਾਇ ॥੧॥{ਪੰਨਾ 593}
Riches and the supernatural spiritual powers of the Siddhas are all emotional attachments; through them, the Naam, the Name of the Lord, does not come to dwell in the mind. Serving the Guru, the mind becomes immaculately pure, and the darkness of spiritual ignorance is dispelled. The jewel of the Naam is revealed in the home of one‟s own being; O Nanak, one merges in celestial bliss. || 1 ||
These Supernatural powers do not lead to emancipation & are attachments, These do not permit the Naam to get set in the mind.
