The root of meditation is the Guru's form; the root of worship is the Guru's feet; the root of all mantra is the Guru's word; and the root of liberation is the Guru's grace.
ध्यानमूलं गुरोर्मूर्तिः पूजामूलं गुरोः पदम् । मन्त्रमूलं गुरोर्वाक्यं मोक्षमूलं गुरोः कृपा
The Guru Gita (Song of the Guru) is a 182-verse scripture from the Uttara Khanda of the Skanda Purana, presented as a dialogue in which Parvati asks Shiva to reveal the nature and glory of the Guru. Shiva teaches the guru-disciple relationship and the identity of Guru and Brahman.
The yogi who, having attained unity, worships me dwelling in all beings, remains in me, regardless of his way of life.
Devotion does not mean running away from your duties; instead, fulfilling your responsibilities is true devotion.
Your daily life is your place of worship, and your religion is how you live it. Bring your entire being into every moment.
