Vijnana Bhairava Tantra – 122

On a single point

वस्त्वन्तरे विद्यमाने सर्ववस्तुषु शून्यता|

तमेव मनसा ध्यात्वा विदितोऽपि प्रशाम्यति||

Vastwantare Vidyamane Sarvavastushu Shunyata|

Tameva Manasa Dhyathwa Viditopi Prashamyati||

While meditating on one object alone, there is an absence of all other objects in the mind. This brings the mind almost to a single pointed contemplation. Meditating on that object alone, with the help of the mind, even if that is still experienced in awareness, the mind attains supreme quietness. - SS

Vijnana Bhairava Tantra – 121

On the dispassionate one

भवत्युद्रेखाद विरक्तस्य यादृशी जायते मतिः|

सा शक्तिः शङ्करी नित्यं भावयेत् तं ततः शिवः ||

Bhavathyudrekhad Viraktasya Yadrushi Jayate Matihi|

Sa Shaktih Shankari Nithyam Bhavayeth Tam Tatah Shivaha||

Contemplating with intensity on the one who is completely dispassionate, the intellect too takes on that quality. That energy of the one with a dispassionate intellect is that of Sankara or one who gives peace. Meditating upon that, one becomes that auspiciousness which is the state of Shiva. – SS

Vijnana Bhairava Tantra – 120

 Meditate on any object

क्वचिद् वस्तुनि विन्यस्य शनैर दृष्टिं निवर्तयेत् |

तज्ज्ञानं चित्त सहितं देवी शून्यालयो भवेत् ||

Kwachidvastuni Vinyasya Shanair Drishtim Nivartayeth|

Tajjnanam Chitta Sahitham Devi Shunyalayo Bhaveth||

Take a particular object, may be a stone, a divine picture or an object of nature. Gaze at that object with intense concentration. Then withdraw the gaze and close your eyes. The impression of the object you see within happens in consciousness. Knowing this to be one with consciousness, the mind at once enters into the temple of nothingness. - SS
