There are many words that are used to describe Liberation in Indian Philosophy. One word that is favored within Tantra is Samarasa. The word Sama means equal or balanced and the word Rasa has a host of meanings, many of which are richly used within Tantra and also Āyurveda. It can be summed up as meaning “taste” or “essence.” Samarasa then refers to the state of experiencing everything as being of one essence. It is a state where one tastes the world in a balanced and ultimately undifferentiated way. It is when the awareness rests in a state of pure Śiva and Śakti.
It is the culmination of Tantric Yoga, the ability to see oneself in the world and the world within oneself, both in perfect harmony. In the Haṭha Yoga Pradīpikā, it is said to be a synonym for samādhi, a state of perfect equilibrium where the individual soul exists in union with the Cosmic Reality.
The person who permanently resides in this state while still embodied is called an Avadhūta, or someone who has shaken off all worldly concerns. Since an Avadhūta has no need of any kind of convention or ordinary worldly involvement, they are sometimes known to behave in strange and inscrutable ways. To encounter such a being is considered to be an enormous blessing, no matter how they may appear.
The Avadhūta Gītā is a Sanskrit text which sings the praise of the Avadhūta and describes the state of resting in Samarasa:
Nirmūla-mūla-rahito hi sadodito’haṃ nirdhūma-dhūma-rahito hi sadodito’ham |
Nirdīpa-dīpa-rahito hi sadodito’haṃ jñānāmṛtaṃ samarasaṃ gaganopamo’ham || III:3 ||
"With fuel and without fuel, I am always burning; with smoke and without smoke, I am always glowing; with flame and without flame, I am always shining; I am immortality in knowledge (the knowledge of immortality), I am equality in essence (samarasa), I am like the sky."
Durbodha bodha-gahano na bhavāmi tāta durlakṣya lakṣya-gahano na bhavāmi tāta |
Āsanna-rūpa-gahano na bhavāmi tāta jñānāmṛtaṃ samarasaṃ gaganopamo’ham || III:8 ||
"I am neither too mysterious nor too difficult to understand; neither too mysterious nor too difficult to contemplate; I am not mysterious, for I live so near; I am immortality in knowledge, I am equality in essence, I am like the sky."
Niṣpāpa-pāpa-dahano hi hutāśano’haṃ Nirdharma-dharma-dahano hi hutāśano’ham |
Nirbandha-bandha-dahano hi hutāśano’haṃ jñānāmṛtaṃ samarasaṃ gaganopamo’ham || III:10 ||
"I am fire that burns religion and irreligion, I am fire that burns merit and sin, I am fire that burns bondage and privilege; I am immortality in knowledge, I am equality in essence, I am like the sky."
Niṣkarma-karma paramaṃ satataṃ karomi nissaṅga-saṅga-rahitaṃ paramaṃ vinodam |
Nirdeha-deha-rahitaṃ satataṃ vinodaṃ jñānāmṛtaṃ samarasaṃ gaganopamo’ham || III:26 ||
"I always work as though the greatest work is no work, I always honour my body as though it exists and does not exist; my greatest sport is to renounce my renouncement; I am knowledge of immortality, I am essence of equanimity, I am like the sky."
Nirjīva-jīva-rahitaṃ satataṃ vibhāti nirbīja-bīja-rahitaṃ satataṃ vibhāti |
Nirvāṇa-bandha-rahitaṃ satataṃ vibhāti jñānāmṛtaṃ samarasaṃ gaganopamo’ham|| III:31 ||
"Constantly shining free from life and death, constantly shining free from seed and seedlessness, constantly shining free from bondage or liberation, I am the knowledge of immortality, I am the essence of equanimity (samarasa), I am the highest sky."
Dhyātā n ate hi hṛdaye na ca te samādhir dhyānaṃ na te hi hṛdaye na bahiḥ pradeśaḥ |
Dhyeyaṃ na ceti hṛdaye na hi vastu-kālo jñānāmṛtaṃ samarasaṃ gaganopamo’ham|| III:41 ||
"Within you there is no one to meditate, no Samādhi yet to be attained. There is no inner meditation, no outer meditation; no object of meditation, no joy of meditation. I am knowledge of immortality, I am essence of equanimity. I am like the sky."
Muñca muñca hi saṃsāraṃ tyāgaṃ muñca hi sarvathā |
Tyāgātyāga-viṣaṃ śuddham amṛtaṃ sahajaṃ dhruvam || III:46 ||
"Give up, give up worldly illusion. Give up renunciation altogether. Cleanse the poison of both renunciation and indulgence and the nectar/immortality of spontaneity remains."
In his Twilight Yoga treatise, Mahendranath says that Samarasa is one of the four key words of the Nāth way of life. The others are Sama or balance, which we have already discussed, Sahaja or spontaneity, and Svecchācāra or doing one’s own true will.
