In a word, Moksha in Hindu philosophy means the goal of human existence. It can be described as liberation from the endless cycle of birth and death (samsara) and even from the illusions of the material world (Maya) that entraps the soul through a web woven of desire, attachment, and ignorance.

Having said this, Moksha is not a negative escape from suffering but a positive realization of the true and eternal nature of pure consciousness. This is nothing but a returning to the origin, merging with the unchangeable reality, Brahman, lying behind all appearances. And Moksha stands for the state when an individual's soul is no longer subjected to the wheel of birth and death and experiences Sat-Chit-Ananda: existence, consciousness, and bliss.

Means of Moksha 

The Bhagavad Gita and the Upanishads tell you about the many paths of Moksha in the different temperaments as follows:

Jnana Yoga- It means the knowledge path-that is, the self or atman is non-difference from Brahman. The seeker breaks this by inquiry and reflection on what he understands as "I."

Bhakti Yoga- That is the way of love and devotion. By such surrender-with faith and emotion-the soul gets purified and lifted beyond the ego.

Karma Yoga- Meaning the path of selfless action. It is by discharging his duties without regard to their results that the ego gets dissolved.

Raja Yoga- It pertains to meditation and mental discipline. It consists of such practices as pranayama, dhyana, and samadhi which are meant for the purification of the mind and self-realization.

It is one of these modern misconceptions about Moksha that it demands abandonment of the world. In actual understanding, it demands renouncing ignorance and not renouncing action. Even in today's times, one can obtain Moksha; a regular employee can achieve inner freedom with the right approach to detachment, mindfulness, and compassion.

To quote the Katha Upanishad (2.3.14): When all desires that dwell in the heart fall away, then the mortal becomes immortal and attains Brahman. It is not in heaven and wealth that the liberation ends, but in knowing the Self as eternal witness within.
