परात्परतरं ध्येयं नित्यमानन्दकारकम् ।
हृदयाकाशमध्यस्थं शुद्धस्फटिकसन्निभम् ॥

parāt parataraṁ dhyeyaṁ nityam ānandakārakam ।
hṛdayākāśa-madhyasthaṁ śuddha-sphaṭika-sannibham ॥

The Guru, who is higher than the highest, who always bestows bliss, and who is seated in the center of the space of the heart, shining like a pure crystal, should be meditated upon.

Shri Guru Gita, verse 113
