The eighteenth chapter of the Bhagavad Gita is Moksha Sanyas Yoga. Arjuna requests the Lord to explain the difference between the two types of renunciations - sanyaas(renunciation of actions) and tyaag(renunciation of desires). Krishna explains that a sanyaasi is one who abandons family and society in order to practise spiritual discipline whereas a tyaagi is one who performs their duties without attachment to the rewards of their actions and dedicating them to the God. Krishna recommends the second kind of renunciation - tyaag. Krishna then gives a detailed analysis of the effects of the three modes of material nature. He declares that the highest path of spirituality is pure, unconditional loving service unto the Supreme Divine Personality, Krishna. If we always remember Him, keep chanting His name and dedicate all our actions unto Him, take refuge in Him and make Him our Supreme goal, then by His grace, we will surely overcome all obstacles and difficulties and be freed from this cycle of birth and death.
Ever engaging even in all actions, one to whom I am the refuge, attains the eternal, immutable State through My grace.OPEN VERSE
Mentally surrendering all actions to Me and accepting Me as the supreme, have your mind ever fixed on Me by resorting to the concentration of your intellect.OPEN VERSE
Having your mind fixed on Me, you will cross over all difficulties through My grace. If, on the other hand, you do not listen out of egotism, you will get destroyed.OPEN VERSE
That you think 'I shall not fight', by relying on egotism, -vain is this determination of yours. (Your) nature impel you!OPEN VERSE
Being bound by your own duty born of nature, O son of Kunti, you, being helpless, will verily do that which you do not wish to do owing to indiscrimination.OPEN VERSE
